Andreas Born ad729bc9ac bonding: require speed/duplex only for 802.3ad, alb and tlb
The patch c4adfc822b ("bonding: make speed, duplex setting consistent
with link state") puts the link state to down if
bond_update_speed_duplex() cannot retrieve speed and duplex settings.
Assumably the patch was written with 802.3ad mode in mind which relies
on link speed/duplex settings. For other modes like active-backup these
settings are not required. Thus, only for these other modes, this patch
reintroduces support for slaves that do not support reporting speed or
duplex such as wireless devices. This fixes the regression reported in
bug 196547 (https://bugzilla.kernel.org/show_bug.cgi?id=196547).

Control the size of the buffer areas via ethtool ring settings.
They aren't really traditional hardware rings, but host API breaks

The default value of send and receive buffer area for host DMA
is much larger than it needs to be. Experimentation shows that
4M receive and 1M send is sufficient.

Jeff Kirsher says:

====================
1GbE Intel Wired LAN Driver Updates 2017-08-08

This series contains updates to e1000e and igb/igbvf.

Gangfeng Huang fixes an issue with receive network flow classification,
where igb_nfc_filter_exit() was not being called in igb_down() which
would cause the filter tables to "fill up" if a user where to change
the adapter settings (such as speed) which requires a reset of the
adapter.

Cliff Spradlin fixes a timestamping issue, where igb was allowing requests
for hardware timestamping even if it was not configured for hardware
transmit timestamping.

Corinna Vinschen removes the error message that there was an "unexpected
SYS WRAP", when it is actually expected.  So remove the message to not
confuse users.

Greg Edwards provides several patches for the mailbox interface between
the PF and VF drivers.  Added a mailbox unlock method to be used to unlock
the PF/VF mailbox by the PF.  Added a lock around the VF mailbox ops to
prevent the VF from sending another message while the PF is still
processing the previous message.  Fixed a "scheduling while atomic" issue
by changing msleep() to mdelay().

Sasha adds support for the next LOM generations i219 (v8 & v9) which
will be available in the next Intel client platform IceLake.

John Linville adds support for a Broadcom PHY to the igb driver, since
there are designs out in the world which use the igb MAC and a third
party PHY.  This allows the driver to load and function as expected on
these designs.

Naftali Goldstein 20fc690f38 iwlwifi: mvm: send delba upon rx ba session timeout
When an RX block-ack session times out, the firmware, which offloads
RX reordering but not the BA session negotiation, stops the session
but doesn't send a DELBA.  This causes the the session to remain
active in the remote device, so no more BA sessions will be
established, causing a severe throughput degradation due to the lack
of aggregation.

Use the new ieee80211_rx_ba_timer_expired API when the ba session timer
expires, since this will tear down the ba session and also send a delba.

The previous API used is intended for drivers that offload the
addba/delba negotiation, but not the rx reordering, while our driver
does the opposite.

This patch depends on "mac80211: add api to start ba session timer
expired flow".

Emmanuel Grumbach a600852a9d iwlwifi: mvm: don't WARN when a legit race happens in A-MPDU
When we start an Rx A-MPDU session, we first get the AddBA
request, then we send an ADD_STA command to the firmware
that will reply with a BAID which is a hardware resource
that tracks the BA session.
This BAID will appear on each and every frame that we get
from the firwmare until the A-MPDU session is torn down.
In the Rx path, we look at this BAID to manage the
reordering buffer.

This flow is inherently racy since the hardware will start
to put the BAID in the frames it receives even if the
firmware hasn't sent the response to the ADD_STA command.
This basically means that the driver can get frames with
a valid BAID that it doesn't know yet.
When that happens, the driver used to WARN.
Fix this by simply not WARN in this case. When the driver
will know abou the BAID, it will initialise the relevant
states and the next frame with a valid BAID will refresh
them.

Avraham Stern 7e39a00d59 iwlwifi: mvm: start mac queues when deferred tx frames are purged
In AP mode, if a station is removed just as it is adding a new stream,
the queue in question will remain stopped and no more TX will happen
in this queue, leading to connection failures and other problems.

This is because under DQA, when tx is deferred because a queue needs
to be allocated, the mac queue for that TID is stopped until the new
stream is added.  If at this point the station that this stream
belongs to is removed, all the deferred tx frames are purged, but the
mac queue is not restarted. As a result, all following tx on this
queue will not be transmitted.

Fix this by starting the relevant mac queues when the deferred tx
frames are purged.

Guillaume Nault 0a0e1a85c8 ppp: fix xmit recursion detection on ppp channels
Commit e5dadc65f9 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.

This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.

Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

Greg Edwards 32652c2ac2 igbvf: add lock around mailbox ops
The PF driver assumes the VF will not send another mailbox message until
the PF has written its reply to the previous message.  If the VF does,
that message will be silently dropped by the PF before it writes its
reply to the mailbox.  This results in a VF mailbox timeout for posted
messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.

Add a lock around the VF mailbox ops to prevent the VF from sending
another message while the PF is still processing the previous one.

Greg Edwards 46b3bb9b47 igb: do not drop PF mailbox lock after read of VF message
When the PF receives a mailbox message from the VF, it grabs the mailbox
lock, reads the VF message from the mailbox, ACKs the message and drops
the lock.

While the PF is performing the action for the VF message, nothing
prevents another VF message from being posted to the mailbox.  The
current code handles this condition by just dropping any new VF messages
without processing them.  This results in a mailbox timeout in the VM
for posted messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.

Given the right sequence of VF messages and mailbox timeouts, this
condition can go on ad infinitum.

Modify the PF mailbox read method to take an 'unlock' argument that
optionally leaves the mailbox locked by the PF after reading the VF
message.  This ensures another VF message is not posted to the mailbox
until after the PF has completed processing the VF message and written
its reply.

Unifies adjusted and unadjusted register value types (e.g. FRAME_POINTER is
 now just a PTR_TO_STACK with zero offset).
Tracks value alignment by means of tracking known & unknown bits.  This
 also replaces the 'reg->imm' (leading zero bits) calculations for (what
 were) UNKNOWN_VALUEs.
If pointer leaks are allowed, and adjust_ptr_min_max_vals returns -EACCES,
 treat the pointer as an unknown scalar and try again, because we might be
 able to conclude something about the result (e.g. pointer & 0x40 is either
 0 or 0x40).
Verifier hooks in the netronome/nfp driver were changed to match the new

actually cause the interrupt.  Rather, it's just bycatch while the
actual interrupt is caused by, for instance, TSICR.TXTS.

The conclusion is that the SYS WRAP is actually expected, so the
"unexpected SYS WRAP" message is entirely bogus and just helps to
confuse users.  Drop it.

Cliff Spradlin 26bd4e2db0 igb: protect TX timestamping from API misuse
HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never
clear. This prevented any future HW timestamping requests to succeed.

Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

Gangfeng Huang 94221ae75c igb: Fix error of RX network flow classification
After add an ethertype filter, if user change the adapter speed several
times, the error "ethtool -N: etype filters are all used" is reported by
igb driver.

In older patch, function igb_nfc_filter_exit() and igb_nfc_filter_restore()
is not paried. igb_nfc_filter_restore() exist in igb_up(), but function
igb_nfc_filter_exit() is exist in __igb_close(). In the process of speed
changing, only igb_nfc_filter_restore() is called, it will take a position
of ethertype bitmap.

Reproduce steps:
Step 1: Add a etype filter by ethtool
$ethtool -N eth0 flow-type ether proto 0x88F8 action 1
Step 2: Change the adapter speed to 100M/full duplex
$ethtool -s eth0 speed 100 duplex full
Step 3: Change the adapter speed to 1000M/full duplex
ethtool -s eth0 speed 1000 duplex full
Repeat step2 and step3, then dmesg the system log, you can find the error
message, add new ethtype filter is also failed.

This fixing is move igb_nfc_filter_exit() from __igb_close() to igb_down()
to make igb_nfc_filter_restore()/igb_nfc_filter_exit() is paired.

Dean Jenkins d0c8f338ab asix: Fix small memory leak in ax88772_unbind()
When Ethernet frames span mulitple URBs, the netdev buffer memory
pointed to by the asix_rx_fixup_info structure remains allocated
during the time gap between the 2 executions of asix_rx_fixup_internal().

This means that if ax88772_unbind() is called within this time
gap to free the memory of the parent private data structure then
a memory leak of the part filled netdev buffer memory will occur.

Therefore, create a new function asix_rx_fixup_common_free() to
free the memory of the netdev buffer and add a call to
asix_rx_fixup_common_free() from inside ax88772_unbind().

Consequently when an unbind occurs part way through receiving
an Ethernet frame, the netdev buffer memory that is holding part
of the received Ethernet frame will now be freed.

Dean Jenkins 960eb4eeaa asix: Ensure asix_rx_fixup_info members are all reset
There is a risk that the members of the structure asix_rx_fixup_info
become unsynchronised leading to the possibility of a malfunction.

For example, rx->split_head was not being set to false after an
error was detected so potentially could cause a malformed 32-bit
Data header word to be formed.

Therefore add function reset_asix_rx_fixup_info() to reset all the
members of asix_rx_fixup_info so that future processing will start
with known initial conditions.

Also, if (skb->len != offset) becomes true then call
reset_asix_rx_fixup_info() so that the processing of the next URB
starts with known initial conditions. Without the call, the check
does nothing which potentially could lead to a malfunction
when the next URB is processed.

In addition, for robustness, call reset_asix_rx_fixup_info() before
every error path's "return 0". This ensures that the next URB is
processed from known initial conditions.

Dean Jenkins 22889dbbd9 asix: Add rx->ax_skb = NULL after usbnet_skb_return()
In asix_rx_fixup_internal() there is a risk that rx->ax_skb gets
reused after passing the Ethernet frame into the network stack via
usbnet_skb_return().

The risks include:

a) asynchronously freeing rx->ax_skb after passing the netdev buffer
   to the NAPI layer which might corrupt the backlog queue.

b) erroneously reusing rx->ax_skb such as calling skb_put_data() multiple
   times which causes writing off the end of the netdev buffer.

Therefore add a defensive rx->ax_skb = NULL after usbnet_skb_return()
so that it is not possible to free rx->ax_skb or to apply
skb_put_data() too many times.

Erez Shitrit 97834eba7c net/mlx5: Delay events till ib registration ends
When mlx5_ib registers itself to mlx5_core as an interface, it will
call mlx5_add_device which will call mlx5_ib interface add callback,
in case the latter successfully returns, only then mlx5_core will add
it to the interface list and async events will be forwarded to mlx5_ib.
Between mlx5_ib interface add callback and mlx5_core adding the mlx5_ib
interface to its devices list, arriving mlx5_core events can be missed
by the new mlx5_ib registering interface.

In other words:
thread 1: mlx5_ib: mlx5_register_interface(dev)
thread 1: mlx5_core: mlx5_add_device(dev)
thread 1: mlx5_core: ctx = dev->add => (mlx5_ib)->mlx5_ib_add
thread 2: mlx5_core_event: **new event arrives, forward to dev_list
thread 1: mlx5_core: add_ctx_to_dev_list(ctx)
/* previous event was missed by the new interface.*/
It is ok to miss events before dev->add (mlx5_ib)->mlx5_ib_add_device
but not after.

We fix this race by accumulating the events that come between the
ib_register_device (inside mlx5_add_device->(dev->add)) till the adding
to the list completes and fire them to the new registering interface
after that.

Saeed Mahameed eeb66cdb68 net/mlx5: Separate between E-Switch and MPFS
Multi-Physical Function Switch (MPFs) is required for when multi-PF
configuration is enabled to allow passing user configured unicast MAC
addresses to the requesting PF.

Before this patch eswitch.c used to manage the HW MPFS l2 table,
E-Switch always (regardless of sriov) enabled vport(0) (NIC PF) vport's
contexts update on unicast mac address list changes, to populate the PF's
MPFS L2 table accordingly.

In downstream patch we would like to allow compiling the driver without
E-Switch functionalities, for that we move MPFS l2 table logic out
of eswitch.c into its own file, and provide Kconfig flag (MLX5_MPFS) to
allow compiling out MPFS for those who don't want Multi-PF support.

NIC PF netdevice will now directly update MPFS l2 table via the new MPFS
API. VF netdevice has no access to MPFS L2 table, so E-Switch will remain
responsible of updating its MPFS l2 table on behalf of its VFs.

Due to this change we also don't require enabling vport(0) (PF vport)
unicast mac changes events anymore, for when SRIOV is not enabled.
Which means E-Switch is now activated only on SRIOV activation, and not
required otherwise.

Add support for SFP hotpluggable modules via sfp-bus and phylink.
This supports both copper and optical SFP modules, which require
different Serdes modes in order to properly negotiate the link.

Optical SFP modules typically require the Serdes link to be talking
1000BaseX mode - this is the gigabit ethernet mode defined by the
802.3 standard.

Copper SFP modules typically integrate a PHY in the module to convert
from Serdes to copper, and the PHY will be configured by the vendor
to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a
SGMII Serdes link.  However, this is vendor defined, so we instead
detect the PHY, switch the link to SGMII mode, and use traditional
PHY based negotiation.

Russell King 9525ae8395 phylink: add phylink infrastructure
The link between the ethernet MAC and its PHY has become more complex
as the interface evolves.  This is especially true with serdes links,
where the part of the PHY is effectively integrated into the MAC.

Serdes links can be connected to a variety of devices, including SFF
modules soldered down onto the board with the MAC, a SFP cage with
a hotpluggable SFP module which may contain a PHY or directly modulate
the serdes signals onto optical media with or without a PHY, or even
a classical PHY connection.

Moreover, the negotiation information on serdes links comes in two
varieties - SGMII mode, where the PHY provides its speed/duplex/flow
control information to the MAC, and 1000base-X mode where both ends
exchange their abilities and each resolve the link capabilities.

This means we need a more flexible means to support these arrangements,
particularly with the hotpluggable nature of SFP, where the PHY can
be attached or detached after the network device has been brought up.

Ethtool information can come from multiple sources:
- we may have a PHY operating in either SGMII or 1000base-X mode, in
  which case we take ethtool/mii data directly from the PHY.
- we may have a optical SFP module without a PHY, with the MAC
  operating in 1000base-X mode - the ethtool/mii data needs to come
  from the MAC.
- we may have a copper SFP module with a PHY whic can't be accessed,
  which means we need to take ethtool/mii data from the MAC.

Phylink aims to solve this by providing an intermediary between the
MAC and PHY, providing a safe way for PHYs to be hotplugged, and
allowing a SFP driver to reconfigure the serdes connection.

Phylink also takes over support of fixed link connections, where the
speed/duplex/flow control are fixed, but link status may be controlled
by a GPIO signal.  By avoiding the fixed-phy implementation, phylink
can provide a faster response to link events: fixed-phy has to wait for
phylib to operate its state machine, which can take several seconds.
In comparison, phylink takes milliseconds.

The correct way to fix this is to associate each MID with the bridge
ports member in it and then drop the reference in case the bridge port
is destroyed, but this will result in a lot more code and will be fixed
in net-next.

For now, upon module removal, traverse the MID list and release each
one.

Ido Schimmel 17b334a876 mlxsw: spectrum_switchdev: Don't warn about valid situations
Some operations in the bridge driver such as MDB deletion are preformed
in an atomic context and thus deferred to a process context by the
switchdev infrastructure.

Therefore, by the time the operation is performed by the underlying
device driver it's possible the bridge port context is already gone.
This is especially true for removal flows, but theoretically can also be
invoked during addition.

Remove the warnings in such situations and return normally.

Willem de Bruijn 1f8b977ab3 sock: enable MSG_ZEROCOPY
Prepare the datapath for refcounted ubuf_info. Clone ubuf_info with
skb_zerocopy_clone() wherever needed due to skb split, merge, resize
or clone.

Split skb_orphan_frags into two variants. The split, merge, .. paths
support reference counted zerocopy buffers, so do not do a deep copy.
Add skb_orphan_frags_rx for paths that may loop packets to receive
sockets. That is not allowed, as it may cause unbounded latency.
Deep copy all zerocopy copy buffers, ref-counted or not, in this path.

The exact locations to modify were chosen by exhaustively searching
through all code that might modify skb_frag references and/or the
the SKBTX_DEV_ZEROCOPY tx_flags bit.

The changes err on the safe side, in two ways.

(1) legacy ubuf_info paths virtio and tap are not modified. They keep
    a 1:1 ubuf_info to sk_buff relationship. Calls to skb_orphan_frags
    still call skb_copy_ubufs and thus copy frags in this case.

(2) not all copies deep in the stack are addressed yet. skb_shift,
    skb_split and skb_try_coalesce can be refined to avoid copying.
    These are not in the hot path and this patch is hairy enough as
    is, so that is left for future refinement.

Ido Schimmel 428b851f56 mlxsw: spectrum_router: Add support for IPv6 routes addition / deletion
Allow directly connected and remote unicast IPv6 routes to be programmed
to the device's tables.

As with IPv4, identical routes - sharing the same destination prefix -
are ordered in a FIB node according to their table ID and then the
metric. While the kernel doesn't share the same trie for the local and
main table, this does happen in the device, so ordering according to
table ID is needed.

Since individual nexthops can be added and deleted in IPv6, each FIB
entry stores a linked list of the rt6_info structs it represents. Upon
the addition or deletion of a nexthop, a new nexthop group is allocated
according to the new configuration and the old one is destroyed.
Identical groups aren't currently consolidated, but will be in a
follow-up patchset.

Ido Schimmel 04b1d4e50e net: core: Make the FIB notification chain generic
The FIB notification chain is currently soley used by IPv4 code.
However, we're going to introduce IPv6 FIB offload support, which
requires these notification as well.

As explained in commit c3852ef7f2 ("ipv4: fib: Replay events when
registering FIB notifier"), upon registration to the chain, the callee
receives a full dump of the FIB tables and rules by traversing all the
net namespaces. The integrity of the dump is ensured by a per-namespace
sequence counter that is incremented whenever a change to the tables or
rules occurs.

In order to allow more address families to use the chain, each family is
expected to register its fib_notifier_ops in its pernet init. These
operations allow the common code to read the family's sequence counter
as well as dump its tables and rules in the given net namespace.

Additionally, a 'family' parameter is added to sent notifications, so
that listeners could distinguish between the different families.

Implement the common code that allows listeners to register to the chain
and for address families to register their fib_notifier_ops. Subsequent
patches will implement these operations in IPv6.

In the future, ipmr and ip6mr will be extended to provide these
notifications as well.

Thomas Petazzoni 213f428f50 net: mvpp2: add support for TX interrupts and RX queue distribution modes
This commit adds the support for two related features:

 - Support for TX interrupts, with one interrupt for each CPU

 - Support for different RX queue distribution modes
   MVPP2_QDIST_SINGLE_MODE where a single interrupt, shared by all
   CPUs, receives the RX events, and MVPP2_QDIST_MULTI_MODE, where the
   per-CPU interrupts used for TX events are also used for RX events.

Since additional interrupts are needed, an update to the Device Tree
binding is needed. However, backward compatibility is preserved with
the old Device Tree binding, by gracefully degrading to the original
behavior, with only one RX interrupt, and TX completion being handled
by an hrtimer.

In preparation to the introduction of TX interrupts and improved RX
queue distribution, this commit introduces the concept of "queue
vector". A queue vector represents a number of RX and/or TX queues,
and an associated NAPI instance and interrupt.

This commit currently only creates a single queue_vector, so there are
no changes in behavior, but it paves the way for additional
queue_vector in the next commits.

Thomas Petazzoni df089aa0ac net: mvpp2: move from cpu-centric naming to "software thread" naming
The PPv2.2 IP has a concept of "software thread", with all registers
of the PPv2.2 mapped 8 times, for concurrent accesses by 8 "software
threads". In addition, interrupts on RX queues are associated to such
"software thread".

For most cases, we map a "software thread" to the more conventional
concept of CPU, but we will soon have one exception: we will have a
model where we have one TX interrupt per CPU (each using one software
thread), and all RX events mapped to another software thread
(associated to another interrupt).

In preparation for this change, it makes sense to change the naming
from MVPP2_MAX_CPUS to MVPP2_MAX_THREADS, and plan for 8 software
threads instead of 4 currently.

Thomas Petazzoni 09f8397553 net: mvpp2: introduce per-port nrxqs/ntxqs variables
Currently, the global variables rxq_number and txq_number hold the
number of per-port TXQs and RXQs. Until now, such numbers were
constant regardless of the driver configuration. As we are going to
introduce different modes for TX and RX queues, these numbers will
depend on the configuration (PPv2.1 vs. PPv2.2, exact queue
distribution logic).

Therefore, as a preparation, we move the number of RXQs and TXQs in
the 'struct mvpp2_port' structure, next to the RXQs and TXQs
descriptor arrays.

For now, they remain initialized to the same default values as
rxq_number/txq_number used to be initialized, but this will change in
future commits.

The only non-mechanical change in this patch is that the check to
verify hardware constraints on the number of RXQs and TXQs is moved
from mvpp2_probe() to mvpp2_port_probe(), since it's now in
mvpp2_port_probe() that we initialize the per-port count of RXQ and
TXQ.

Robin Murphy 13cb8a5845 qtnfmac: Tidy up DMA mask setting
As the only caller of dma_supported() outside of DMA API internals, the
qtfnmac driver stands out and invites scrutiny. Thankfully, it's not
being used for evil, but it is entirely redundant, since it open-codes a
check that the DMA mask setting functions are going to perform anyway.
In fact, the whole qtnf_pcie_init_dma_mask() function is nothing more
than a rather long-winded implementation of dma_set_mask_and_coherent(),
so let's just use that directly.

Now that we provide offload indication using the nexthop's flags we must

Ido Schimmel 1353ee7073 mlxsw: spectrum_router: Don't check state when refreshing offload indication
Previous patch removed the reliance on the counter in the FIB info to
set the offload indication, so we no longer need to keep an offload
state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD
flag in each nexthop.

This is also necessary because we're going to need to refresh the
offload indication whenever the nexthop group associated with the FIB
entry is refreshed. Current check would prevent us from marking a newly
resolved nexthop as offloaded if the FIB entry is already marked as
offloaded.

This patch implements transparent fail over from synthetic NIC to
SR-IOV virtual function NIC in Hyper-V environment. It is a better
alternative to using bonding as is done now. Instead, the receive and
transmit fail over is done internally inside the driver.

Using bonding driver has lots of issues because it depends on the
script being run early enough in the boot process and with sufficient
information to make the association. This patch moves all that
functionality into the kernel.

The cited commit introduced the following new enum value in file
include/linux/mlx4/device.h:

    QUERY_DEV_CAP_DIAG_RPRT_PER_PORT

However, it failed to introduce a corresponding entry in function
dump_dev_cap_flags2() for outputting a line in the message log
when this capability bit is set.

The change here fixes that omission.

The last patch added the dependency on 'OF && HAS_IOMEM' but left

For compile-testing purposes, we don't really need this anyway,

is present on all architectures we do meaningful compile-testing on
(the exception being arch/um).

Niklas Söderlund fbf3d034f2 ravb: add workaround for clock when resuming with WoL enabled
The renesas-cpg-mssr clock driver are not yet aware of PSCI sleep where
power is cut to the SoC. When resuming from this state with WoL enabled
the enable count of the ravb clock is 1 and the clock driver thinks the
clock is already on when PM core enables the clock and increments the
enable count to 2. This will result in the ravb driver failing to talk
to the hardware since the module clock is off. Work around this by
forcing the enable count to 0 and then back to 2 when resuming with WoL
enabled.

This workaround should be reverted once the renesas-cpg-mssr clock
driver becomes aware of this PSCI sleep behavior.

Niklas Söderlund 3e3d647715 ravb: add wake-on-lan support via magic packet
WoL is enabled in the suspend callback by setting MagicPacket detection
and disabling all interrupts expect MagicPacket. In the resume path the
driver needs to reset the hardware to rearm the WoL logic, this prevents
the driver from simply restoring the registers and to take advantage of
that ravb was not suspended to reduce resume time. To reset the
hardware the driver closes the device, sets it in reset mode and reopens
the device just like it would do in a normal suspend/resume scenario
without WoL enabled, but it both closes and opens the device in the
resume callback since the device needs to be reset for WoL to work.

One quirk needed for WoL is that the module clock needs to be prevented
from being switched off by Runtime PM. To keep the clock alive the
suspend callback need to call clk_enable() directly to increase the
usage count of the clock. Then when Runtime PM decreases the clock usage
count it won't reach 0 and be switched off.

K. Den be73b3043b vxlan: fix remcsum when GRO on and CHECKSUM_PARTIAL boundary is outer UDP
In the case that GRO is turned on and the original received packet is
CHECKSUM_PARTIAL, if the outer UDP header is exactly at the last
csum-unnecessary point, which for instance could occur if the packet
comes from another Linux guest on the same Linux host, we have to do
either remcsum_adjust or set up CHECKSUM_PARTIAL again with its
csum_start properly reset considering RCO.

However, since b7fe10e5ebac("gro: Fix remcsum offload to deal with frags
in GRO") that barrier in such case could be skipped if GRO turned on,
hence we pass over it and the inner L4 validation mistakenly reckons
it as a bad csum.

This patch makes remcsum_offload being reset at the same time of GRO
remcsum cleanup, so as to make it work in such case as before.

This patch adds the driver for ethernet controller on MT7622 SoC. It has
the similar handling logic as the previously MT7623 does, but there are
additions against with MT7623 SoC, the shared SGMII given for the dual
GMACs and including 5-ports 10/100 embedded switch support (ESW) as the
GMAC1 option, thus more clocks consumers for the extra feature are
introduced here. So for ease portability and maintenance, those
differences all are being kept inside the platform data as other drivers
usually do. Currently testing successfully is done with those patches for
the conditions such as GMAC2 with IP1001 PHY via RGMII and GMAC1/2 with
RTL8211F PHY via SGMII.

Grygorii Strashko 0d5f54fec0 net: ethernet: ti: cpts: fix tx timestamping timeout
With the low speed Ethernet connection CPDMA notification about packet
processing can be received before CPTS TX timestamp event, which is set
when packet actually left CPSW while cpdma notification is sent when packet
pushed in CPSW fifo.  As result, when connection is slow and CPU is fast
enough TX timestamping is not working properly.

Fix it, by introducing TX SKB queue to store PTP SKBs for which Ethernet
Transmit Event hasn't been received yet and then re-check this queue
with new Ethernet Transmit Events by scheduling CPTS overflow
work more often (every 1 jiffies) until TX SKB queue is not empty.

Side effect of this change is:
 - User space tools require to take into account possible delay in TX
timestamp processing (for example ptp4l works with tx_timestamp_timeout=400
under net traffic and tx_timestamp_timeout=25 in idle).
