Sukadev Bhattiprolu 8f1c0fd2c8 ibmvnic: fix a race between open and reset
__ibmvnic_reset() currently reads the adapter->state before getting the
rtnl and saves that state as the "target state" for the reset. If this
read occurs when adapter is in PROBED state, the target state would be
PROBED.

Just after the target state is saved, and before the actual reset process
is started (i.e before rtnl is acquired) if we get an ibmvnic_open() call
we would move the adapter to OPEN state.

But when the reset is processed (after ibmvnic_open()) drops the rtnl),
it will leave the adapter in PROBED state even though we already moved
it to OPEN.

To fix this, use the RTNL to improve serialization when reading/updating
the adapter state. i.e determine the target state of a reset only after
getting the RTNL. And if a reset is in progress during an open, simply
set the target state of the adapter and let the reset code finish the
open (like we currently do if failover is pending).

One twist to this serialization is if the adapter state changes when we
drop the RTNL to update the link state. Account for this by checking if
there was an intervening open and update the target state for the reset
accordingly (see new comments in the code). Note that only the reset
functions and ibmvnic_open() can set the adapter to OPEN state and this
must happen under rtnl.

Brett Creeley a6aa7c8f99 ice: Account for port VLAN in VF max packet size calculation
Currently if an AVF driver doesn't account for the possibility of a
port VLAN when determining its max packet size then packets at MTU will
be dropped. It is not the VF driver's responsibility to account for a
port VLAN so fix this. To fix this, do the following:

1. Add a function that determines the max packet size a VF is allowed by
   using the port's max packet size and whether the VF is in a port
   VLAN. If a port VLAN is configured then a VF's max packet size will
   always be the port's max packet size minus VLAN_HLEN. Otherwise it
   will be the port's max packet size.

2. Use this function to verify the max packet size from the VF.

3. If there is a port VLAN configured then add 4 bytes (VLAN_HLEN) to
   the VF's max packet size configuration.

Also, the VIRTCHNL_OP_GET_VF_RESOURCES message provides the capability
to communicate a VF's max packet size. Use the new function for this
purpose.

Brett Creeley 37b52be260 ice: Set trusted VF as default VSI when setting allmulti on
Currently the PF will only set a trusted VF as the default VSI when it
requests FLAG_VF_UNICAST_PROMISC over VIRTCHNL. However, when
FLAG_VF_MULTICAST_PROMISC is set it's expected that the trusted VF will
see multicast packets that don't have a matching destination MAC in the
devices internal switch. Fix this by setting the trusted VF as the
default VSI if either FLAG_VF_UNICAST_PROMISC or
FLAG_VF_MULTICAST_PROMISC is set.

Dave Ertman 7dcf7aa01c ice: report correct max number of TCs
In the driver currently, we are reporting max number of TCs
to the DCBNL callback as a kernel define set to 8.  This is
preventing userspace applications performing DCBx to correctly
down map the TCs from requested to actual values.

Report the actual max TC value to userspace from the capability

Slawomir Laba 92c6058024 i40e: Fix flow for IPv6 next header (extension header)
When a packet contains an IPv6 header with next header which is
an extension header and not a protocol one, the kernel function
skb_transport_header called with such sk_buff will return a
pointer to the extension header and not to the TCP one.

The above explained call caused a problem with packet processing
for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6.
The extension header was not skipped at all.

The ipv6_skip_exthdr function does check if next header of the IPV6
header is an extension header and doesn't modify the l4_proto pointer
if it points to a protocol header value so its safe to omit the
comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can
return value -1. This means that the skipping process failed
and there is something wrong with the packet so it will be dropped.

Sven Van Asbroeck 966df6ded2 lan743x: sync only the received area of an rx ring buffer
On cpu architectures w/o dma cache snooping, dma_unmap() is a
is a very expensive operation, because its resulting sync
needs to invalidate cpu caches.

Increase efficiency/performance by syncing only those sections
of the lan743x's rx ring buffers that are actually in use.

Sven Van Asbroeck a8db76d40e lan743x: boost performance on cpu archs w/o dma cache snooping
The buffers in the lan743x driver's receive ring are always 9K,
even when the largest packet that can be received (the mtu) is
much smaller. This performs particularly badly on cpu archs
without dma cache snooping (such as ARM): each received packet
results in a 9K dma_{map|unmap} operation, which is very expensive
because cpu caches need to be invalidated.

Careful measurement of the driver rx path on armv7 reveals that
the cpu spends the majority of its time waiting for cache
invalidation.

Optimize by keeping the rx ring buffer size as close as possible
to the mtu. This limits the amount of cache that requires
invalidation.

This optimization would normally force us to re-allocate all
ring buffers when the mtu is changed - a disruptive event,
because it can only happen when the network interface is down.

Remove the need to re-allocate all ring buffers by adding support
for multi-buffer frames. Now any combination of mtu and ring
buffer size will work. When the mtu changes from mtu1 to mtu2,
consumed buffers of size mtu1 are lazily replaced by newly
allocated buffers of size mtu2.

These optimizations double the rx performance on armv7.
Third parties report 3x rx speedup on armv8.

Tested with iperf3 on a freescale imx6qp + lan7430, both sides
set to mtu 1500 bytes, measure rx performance:

Vladimir Oltean 3af409ca27 net: enetc: fix destroyed phylink dereference during unbind
The following call path suggests that calling unregister_netdev on an
interface that is up will first bring it down.

enetc_pf_remove
-> unregister_netdev
   -> unregister_netdevice_queue
      -> unregister_netdevice_many
         -> dev_close_many
            -> __dev_close_many
               -> enetc_close
                  -> enetc_stop
                     -> phylink_stop

However, enetc first destroys the phylink instance, then calls
unregister_netdev. This is already dissimilar to the setup (and error
path teardown path) from enetc_pf_probe, but more than that, it is buggy
because it is invalid to call phylink_stop after phylink_destroy.

So let's first unregister the netdev (and let the .ndo_stop events
consume themselves), then destroy the phylink instance, then free the
netdev.

Aya Levin 432119de33 net/mlx5: Add cyc2time HW translation mode support
Device timestamp can be in real time mode (cycles to time translation is
offloaded into the Hardware). With real time mode, HW provides timestamp
which is already translated into nanoseconds.

With this mode, driver adjusts both the HW and timecounter (to keep
clock_info_page updated) using callbacks: adjfreq, adjtime and settime.
HW clock modifications are done via MTUTC access reg commands. Driver is
allowed to modify HW real time clock only if MCAM ptpcyc2realtime_modify
capability is set.

Add MTUTC set function to be used for configuring the HW real time
clock. Modify existing code to support both internal timer (with
conversion via timecounter_cyc2time() and real time (no conversions).

Align the signatures of the helpers converting from timestamp to
nanoseconds. With that, when allocating a queue assign the corresponding
callback with respect to the capability.

Adjust 1PPS timestamp calculation flows based on the timestamp mode.

Cyc2time offload brings two major advantages:
- Improve MTAE (Max Time Absolute Error) for HW TS by up to 160 ns over a
  100% loaded CPU.
- Faster data-path timestamp to nanoseconds, as translation is
  lock-less and done in HW.

On real time mode, timestamp format is 32 high bits of seconds and 32
low bits of nanoseconds. On some flows, driver shall convert this format
into nanoseconds wall-clock with REAL_TIME_TO_NS macro.

HW supports a single clock, and it is shared by all functions on a
device. In case real time clock is used, it is recommended to use
a single GM to all device's functions.

The work queue is used to queue reset requests like CHANGE-PARAM or
FAILOVER resets for the worker thread. When the adapter is being removed
the adapter state is set to VNIC_REMOVING and the work queue is flushed
so no new work is added. However the check for adapter being removed is
racy in that the adapter can go into REMOVING state just after we check
and we might end up adding work just as it is being flushed (or after).

The ->rwi_lock is already being used to serialize queue/dequeue work.
Extend its usage ensure there is no race when scheduling/flushing work.

Vladimir Oltean 1f778d500d net: mscc: ocelot: avoid type promotion when calling ocelot_ifh_set_dest
Smatch is confused by the fact that a 32-bit BIT(port) macro is passed
as argument to the ocelot_ifh_set_dest function and warns:

ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?

The destination port mask is copied into a 12-bit field of the packet,
starting at bit offset 67 and ending at 56.

So this DSA tagging protocol supports at most 12 bits, which is clearly
less than 32. Attempting to send to a port number > 12 will cause the
packing() call to truncate way before there will be 32-bit truncation
due to type promotion of the BIT(port) argument towards u64.

Therefore, smatch's fears that BIT(port) will do the wrong thing and
cause unexpected truncation for "port" values >= 32 are unfounded.
Nonetheless, let's silence the warning by explicitly passing an u64
value to ocelot_ifh_set_dest, such that the compiler does not need to do
a questionable type promotion.

Vladimir Oltean 0a6f17c6ae net: dsa: tag_ocelot_8021q: add support for PTP timestamping
For TX timestamping, we use the felix_txtstamp method which is common
with the regular (non-8021q) ocelot tagger. This method says that skb
deferral is needed, prepares a timestamp request ID, and puts a clone of
the skb in a queue waiting for the timestamp IRQ.

felix_txtstamp is called by dsa_skb_tx_timestamp() just before the
tagger's xmit method. In the tagger xmit, we divert the packets
classified by dsa_skb_tx_timestamp() as PTP towards the MMIO-based
injection registers, and we declare them as dead towards dsa_slave_xmit.
If not PTP, we proceed with normal tag_8021q stuff.

Then the timestamp IRQ fires, the clone queued up from felix_txtstamp is
matched to the TX timestamp retrieved from the switch's FIFO based on
the timestamp request ID, and the clone is delivered to the stack.

On RX, thanks to the VCAP IS2 rule that redirects the frames with an
EtherType for 1588 towards two destinations:
- the CPU port module (for MMIO based extraction) and
- if the "no XTR IRQ" workaround is in place, the dsa_8021q CPU port
the relevant data path processing starts in the ptp_classify_raw BPF
classifier installed by DSA in the RX data path (post tagger, which is
completely unaware that it saw a PTP packet).

This time we can't reuse the same implementation of .port_rxtstamp that
also works with the default ocelot tagger. That is because felix_rxtstamp
is given an skb with a freshly stripped DSA header, and it says "I don't
need deferral for its RX timestamp, it's right in it, let me show you";
and it just points to the header right behind skb->data, from where it
unpacks the timestamp and annotates the skb with it.

The same thing cannot happen with tag_ocelot_8021q, because for one
thing, the skb did not have an extraction frame header in the first
place, but a VLAN tag with no timestamp information. So the code paths
in felix_rxtstamp for the regular and 8021q tagger are completely
independent. With tag_8021q, the timestamp must come from the packet's
duplicate delivered to the CPU port module, but there is potentially
complex logic to be handled [ and prone to reordering ] if we were to
just start reading packets from the CPU port module, and try to match
them to the one we received over Ethernet and which needs an RX
timestamp. So we do something simple: we tell DSA "give me some time to
think" (we request skb deferral by returning false from .port_rxtstamp)
and we just drop the frame we got over Ethernet with no attempt to match
it to anything - we just treat it as a notification that there's data to
be processed from the CPU port module's queues. Then we proceed to read
the packets from those, one by one, which we deliver up the stack,
timestamped, using netif_rx - the same function that any driver would
use anyway if it needed RX timestamp deferral. So the assumption is that
we'll come across the PTP packet that triggered the CPU extraction
notification eventually, but we don't know when exactly. Thanks to the
VCAP IS2 trap/redirect rule and the exclusion of the CPU port module
from the flooding replicators, only PTP frames should be present in the
CPU port module's RX queues anyway.

There is just one conflict between the VCAP IS2 trapping rule and the
semantics of the BPF classifier. Namely, ptp_classify_raw() deems
general messages as non-timestampable, but still, those are trapped to
the CPU port module since they have an EtherType of ETH_P_1588. So, if
the "no XTR IRQ" workaround is in place, we need to run another BPF
classifier on the frames extracted over MMIO, to avoid duplicates being
sent to the stack (once over Ethernet, once over MMIO). It doesn't look
like it's possible to install VCAP IS2 rules based on keys extracted
from the 1588 frame headers.

Since the felix DSA driver will need to poll the CPU port module for

an Extraction Frame Header, and then an skb, from a CPU extraction
group.

We abuse the struct ocelot_ops :: port_to_netdev function a little bit,
in order to retrieve the DSA port net_device or the ocelot switchdev
net_device based on the source port information from the Extraction
Frame Header, but it's all in the benefit of code simplification -
netdev_alloc_skb needs it. Originally, the port_to_netdev method was

driver call some helpers exported by the DSA tagger. Among other things,
this allows us to get rid of the strange cpu_to_be32 when transmitting
the Injection Frame Header on ocelot, since the packing API uses
network byte order natively (when "quirks" is 0).

The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and
the cpu extraction queue mask to something, but the code doesn't do it,
so we don't do it either.

Also create some shim definitions, since the DSA tagger can be compiled

The ocelot_rx_frame_word() function can return a negative error code,
however this isn't being checked for consistently. Errors being ignored

Also, some constructs can be simplified by using "goto" instead of

Vladimir Oltean d7795f8f26 net: mscc: ocelot: only drain extraction queue on error
It appears that the intention of this snippet of code is to not exit
ocelot_xtr_irq_handler() while in the middle of extracting a frame.
The problem in extracting it word by word is that future extraction
attempts are really easy to get desynchronized, since the IRQ handler
assumes that the first 16 bytes are the IFH, which give further
information about the frame, such as frame length.

But during normal operation, "err" will not be 0, but 4, set from here:

		for (i = 0; i < OCELOT_TAG_LEN / 4; i++) {
			err = ocelot_rx_frame_word(ocelot, grp, true, &ifh[i]);
			if (err != 4)
				break;
		}

		if (err != 4)
			break;

In that case, draining the extraction queue is a no-op. So explicitly
make this code execute only on negative err.

Michael Chan dab62e7c2d bnxt_en: Implement faster recovery for firmware fatal error.
During some fatal firmware error conditions, the PCI config space
register 0x2e which normally contains the subsystem ID will become
0xffff.  This register will revert back to the normal value after
the chip has completed core reset.  If we detect this condition,
we can poll this config register immediately for the value to revert.
Because we use config read cycles to poll this register, there is no
possibility of Master Abort if we happen to read it during core reset.
This speeds up recovery significantly as we don't have to wait for the
conservative min_time before polling MMIO to see if the firmware has
come out of reset.  As soon as this register changes value we can
proceed to re-initialize the device.

Move clock initialization to earlier in the process so we do not waste as

Also enable the clock regardless of whether the controller is using an MDIO

Maciej does cleanups on the following drivers.
For i40e, removes redundant check for XDP prog, cleans up no longer
relevant information, and removes an unused function argument.
For ice, removes local variable use, instead returning values directly.
Moves skb pointer from buffer to ring and removes an unneeded check for
xdp_prog in zero copy path. Also removes a redundant MTU check when
changing it.
For i40e, ice, and ixgbe, stores the rx_offset in the Rx ring as
the value is constant so there's no need for continual calls.

Vladimir Oltean 421741ea56 net: mscc: ocelot: offload bridge port flags to device
We should not be unconditionally enabling address learning, since doing
that is actively detrimential when a port is standalone and not offloading
a bridge. Namely, if a port in the switch is standalone and others are
offloading the bridge, then we could enter a situation where we learn an
address towards the standalone port, but the bridged ports could not
forward the packet there, because the CPU is the only path between the
standalone and the bridged ports. The solution of course is to not
enable address learning unless the bridge asks for it.

We need to set up the initial port flags for no learning and flooding
everything, and also when the port joins and leaves the bridge.
The flood configuration was already configured ok for standalone mode
in ocelot_init, we just need to disable learning in ocelot_init_port.

Vladimir Oltean e18f4c18ab net: switchdev: pass flags and mask to both {PRE_,}BRIDGE_FLAGS attributes
This switchdev attribute offers a counterproductive API for a driver
writer, because although br_switchdev_set_port_flag gets passed a
"flags" and a "mask", those are passed piecemeal to the driver, so while
the PRE_BRIDGE_FLAGS listener knows what changed because it has the
"mask", the BRIDGE_FLAGS listener doesn't, because it only has the final
value. But certain drivers can offload only certain combinations of
settings, like for example they cannot change unicast flooding
independently of multicast flooding - they must be both on or both off.
The way the information is passed to switchdev makes drivers not
expressive enough, and unable to reject this request ahead of time, in
the PRE_BRIDGE_FLAGS notifier, so they are forced to reject it during
the deferred BRIDGE_FLAGS attribute, where the rejection is currently
ignored.

This patch also changes drivers to make use of the "mask" field for edge
detection when possible.

Furthermore, since there is already a function responsible for bumping

wait_for_resync is unreliable - if it timeouts, priv_rx will be freed
anyway. However, mlx5e_ktls_handle_get_psv_completion will be called

if a CQ error happened, and ICOSQ stopped, but later on the queues are
destroyed, and ICOSQ is flushed with mlx5e_free_icosq_descs.

This patch converts the lifecycle of priv_rx to fully refcount-based, so

The commit mentioned below has split the parameters of ICOSQ and async
ICOSQ, but it contained a typo: the CQ parameters were swapped for ICOSQ
and async ICOSQ. Async ICOSQ is longer than the normal ICOSQ, and the CQ
size must be the same as the size of the corresponding SQ, but due to
this bug, the CQ of async ICOSQ was much shorter than async ICOSQ
itself. It led to overflows of the CQ with such messages in dmesg, in
particular, when running multiple kTLS-offloaded streams:

mlx5e_reset_{rx,tx}_moderation is called to update the fields, however,

Vignesh Raghavendra 86e8b070b2 net: ti: am65-cpsw-nuss: Add switchdev support
J721e, J7200 and AM64 have multi port switches which can work in multi
mac mode and in switch mode. Add support for configuring this HW in
switch mode using devlink and switchdev notifiers.

Support is similar to existing CPSW switchdev implementation of TI's 32 bit
platform like AM33/AM43/AM57.

To enable switch mode:
devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime

All configuration is implemented via switchdev API and notifiers.
Supported:
      - SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS
      - SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS
      - SWITCHDEV_ATTR_ID_PORT_STP_STATE
      - SWITCHDEV_OBJ_ID_PORT_VLAN
      - SWITCHDEV_OBJ_ID_PORT_MDB
      - SWITCHDEV_OBJ_ID_HOST_MDB

Hence AM65 CPSW switchdev driver supports:
     - FDB offloading
     - MDB offloading
     - VLAN filtering and offloading
     - STP

Vignesh Raghavendra 58356eb31d net: ti: am65-cpsw-nuss: Add devlink support
AM65 NUSS ethernet switch on K3 devices can be configured to work either
in independent mac mode where each port acts as independent network
interface (multi mac) or switch mode.

Add devlink hooks to provide a way to switch b/w these modes.

Rationale to use devlink instead of defaulting to bridge mode is that
SoC use cases require to support multiple independent MAC ports with no
switching so that users can use software bridges with multi-mac
configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching
between multi mac and switch mode requires significant Port and ALE
reconfiguration, therefore is easier to be made as part of mode change
devlink hooks. It also allows to keep user interface similar to what
was implemented for the previous generation of TI CPSW IP
(on AM33/AM43/AM57 SoCs).

Subbaraya Sundeep 242da43921 octeontx2-af: cn10k: Add support for programmable channels
NIX uses unique channel numbers to identify the packet sources/sinks
like CGX,LBK and SDP. The channel numbers assigned to each block are
hardwired in CN9xxx silicon.
The fixed channel numbers in CN9xxx are:

0x0 | a << 8 | b            - LBK(0..3)_CH(0..63)
0x0 | a << 8                - Reserved
0x700 | a                   - SDP_CH(0..255)
0x800 | a << 8 | b << 4 | c - CGX(0..7)_LMAC(0..3)_CH(0..15)

All the channels in the above fixed enumerator(with maximum
number of blocks) are not required since some chips
have less number of blocks.
For CN10K silicon the channel numbers need to be programmed by
software in each block with the base channel number and range of
channels. This patch calculates and assigns the channel numbers
to efficiently distribute the channel number range(0-4095) among
all the blocks. The assignment is made based on the actual number of
blocks present and also contiguously leaving no holes.
The channel numbers remaining after the math are used as new CPT
replay channels present in CN10K. Also since channel numbers are
not fixed the transmit channel link number needed by AF consumers
is calculated by AF and sent along with nix_lf_alloc mailbox response.

Hariprasad Kelam 91c6945ea1 octeontx2-af: cn10k: Add RPM MAC support
OcteonTx2's next gen platform the CN10K has RPM MAC which has a
different serdes when compared to CGX MAC. Though the underlying
HW is different, the CSR interface has been designed largely inline
with CGX MAC, with few exceptions though. So we are using the same
CGX driver for RPM MAC as well and will have a different set of APIs
for RPM where ever necessary.

This patch adds initial support for CN10K's RPM MAC i.e. the driver
registration, communication with firmware etc. For communication with
firmware, RPM provides a different IRQ when compared to CGX.
The CGX and RPM blocks support different features. Currently few
features like ptp, flowcontrol and higig are not supported by RPM. This
patch adds new mailbox message "CGX_FEATURES_GET" to get the list of
features supported by underlying MAC.

RPM has different implementations for RX/TX stats. Unlike CGX,
bar offset of stat registers are different. This patch adds
support to access the same and dump the values in debugfs.

Stefan Chulski bf270fa3c4 net: mvpp2: add FCA RXQ non occupied descriptor threshold
The firmware needs to monitor the RX Non-occupied descriptor
bits for flow control to move to XOFF mode.
These bits need to be unmasked to be functional, but they will
not raise interrupts as we leave the RX exception summary
bit in MVPP2_ISR_RX_TX_MASK_REG clear.

Stefan Chulski d07ea73f37 net: mvpp2: increase BM pool and RXQ size
BM pool and RXQ size increased to support Firmware Flow Control.
Minimum depletion thresholds to support FC are 1024 buffers.
BM pool size increased to 2048 to have some 1024 buffers
space between depletion thresholds and BM pool size.

Jumbo frames require a 9888B buffer, so memory requirements
for data buffers increased from 7MB to 24MB.

Stefan Chulski 60dcd6b7d9 net: mvpp2: always compare hw-version vs MVPP21
Currently we have PP2v1 and PP2v2 hw-versions, with some different
handlers depending upon condition hw_version = MVPP21/MVPP22.
In a future there will be also PP2v3. Let's use now the generic
"if equal/notEqual MVPP21" for all cases instead of "if MVPP22".

This patch does not change any functionality.
It is not intended to introduce PP2v3.
It just modifies MVPP21/MVPP22 check-condition
bringing it to generic and unified form correct for new-code
introducing and PP2v3 net-next generation.

Nathan Rossi 8a28af7a3e net: ethernet: aquantia: Handle error cleanup of start on open
The aq_nic_start function can fail in a variety of cases which leaves
the device in broken state.

An example case where the start function fails is the
request_threaded_irq which can be interrupted, resulting in a EINTR
result. This can be manually triggered by bringing the link up (e.g. ip
link set up) and triggering a SIGINT on the initiating process (e.g.
Ctrl+C). This would put the device into a half configured state.
Subsequently bringing the link up again would cause the napi_enable to
BUG.

In order to correctly clean up the failed attempt to start a device call
aq_nic_stop.

The running fw.psid version is in decimal format but the stored
fw.psid is in hex format.  This can mislead the user to reset the
NIC to activate the stored version to become the running version.

Fix it to display the stored fw.psid in decimal format.
