Shahar S Matityahu 54f3f994e9 iwlwifi: fix D3 debug data buffer memory leak
If the driver is unloaded when D3 debug data pulling is enabled
but not triggered, it doesn't release the data buffer.

Fix this by adding iwl_fw_runtime_free and calling it from the
relevant places.

Emmanuel Grumbach 82715ac71e iwlwifi: mvm: fix regulatory domain update when the firmware starts
When the firmware starts, it doesn't have any regulatory
information, hence it uses the world wide limitations. The
driver can feed the firmware with previous knowledge that
was kept in the driver, but the firmware may still not
update its internal tables.

This happens when we start a BSS interface, and then the
firmware can change the regulatory tables based on our
location and it'll use more lenient, location specific
rules. Then, if the firmware is shut down (when the
interface is brought down), and then an AP interface is
created, the firmware will forget the country specific
rules.

The host will think that we are in a certain country that
may allow channels and will try to teach the firmware about
our location, but the firmware may still not allow to drop
the world wide limitations and apply country specific rules
because it was just re-started.

In this case, the firmware will reply with MCC_RESP_ILLEGAL
to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let
the upper layers (cfg80211 / hostapd) know that the channel
list they know about has been updated.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=201105

When read the ACPI data to find out the WGDS, the DATA_SIZE is never

From the above format, it gives 19 numbers, but our driver is hardcode

Fix it to pass then can parse the data into our wgds table.

Recent commit has added the reservation of RSS context.  This requires
bnxt_hwrm_vnic_qcaps() to be called before allocating any RSS contexts.
The bnxt_hwrm_vnic_qcaps() call sets up proper flags that will
determine how many RSS contexts to allocate to support NTUPLE.

This causes a regression that too many RSS contexts are being reserved
and causing resource shortage when enabling many VFs.  Fix it by calling
bnxt_hwrm_vnic_qcaps() earlier.

Michal Kalderon 291d57f67d qed: Fix rdma_info structure allocation
Certain flows need to access the rdma-info structure, for example dcbx
update flows. In some cases there can be a race between the allocation or
deallocation of the structure which was done in roce start / roce stop and
an asynchrounous dcbx event that tries to access the structure.
For this reason, we move the allocation of the rdma_info structure to be
similar to the iscsi/fcoe info structures which are allocated during device
setup.
We add a new field of "active" to the struct to define whether roce has
already been started or not, and this is checked instead of whether the
pointer to the info structure.

====================
pull-request: can 2018-11-09

this is a pull request of 20 patches for net/master.

First we have a patch by Oliver Hartkopp which changes the raw socket's
raw_sendmsg() to return an error value if the user tries to send a CANFD
frame to a CAN-2.0 device.

The next two patches are by Jimmy Assarsson and fix potential problems
in the kvaser_usb driver.

YueHaibing's patches for the ucan driver fix a compile time warning and
remove a duplicate include.

Eugeniu Rosca patch adds more binding documentation to the rcar_can
driver bindings. The next two patches are by Fabrizio Castro for the
rcar_can driver and fixes a problem in the driver's probe function and
document the r8a774a1 binding.

Lukas Wunner's patch fixes a recpetion problem in hi311x driver by
switching from edge to level triggered interruts.

The next three patches all target the flexcan driver. Pankaj Bansal's
patch unconditionally unlocks the last mailbox used for RX. Alexander
Stein provides a better workaround for a hardware limitation when
sending RTR frames, by using the last mailbox for TX, resulting in fewer
lost frames. The patch by me simplyfies the driver, by making a runtime
value a compile time constant.

The following 4 patches are by me and provide the groundwork for the
next patches by Oleksij Rempel. To avoid code duplication common code in
the common CAN driver infrastructure is factured out and error handling
is cleaned up.

The next 4 patches are by Oleksij Rempel and fix the problem in the
flexcan driver that other processes see TX frames arrive out of order
with ragards to a RX'ed frame (which are send by a different system on
the CAN bus as the result of our TX frame).

Sudarsana Reddy Kalluru 77e461d14e bnx2x: Assign unique DMAE channel number for FW DMAE transactions.
Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW
uses this channel for DMAE operations (e.g., TIME_SYNC implementation).
Driver also uses the same channel 0 for DMAE operations for some of the PFs
(e.g., PF0 on Port0). This could lead to concurrent access to the DMAE
channel by FW and driver which is not legal. Hence need to assign unique
DMAE id for FW.
Currently following DMAE channels are used by the clients,
  MFW - OCBB/OCSD functionality uses DMAE channel 14/15
  Driver 0-3 and 8-11 (for PF dmae operations)
         4 and 12 (for stats requests)
Assigning unique dmae_id '13' to the FW.

The mv88e6161 would sometime fail to probe with a timeout waiting for
the switch to complete an operation. This operation is supposed to
clear the statistics counters. However, due to a read/modify/write,
without the needed mask, the operation actually carried out was more
random, with invalid parameters, resulting in the switch not
responding. We need to preserve the histogram mode bits, so apply a

Although driver disables the rings on down, this is not enough.
Due to internal HW design, during subsequent initialization
NIC sometimes may reuse RX descriptors cache and write to the

That's get catched by IOMMU on host.

Oleksij Rempel ed72bc8bcb can: flexcan: handle tx-complete CAN frames via rx-offload infrastructure
Current flexcan driver will put TX-ECHO in regular unsorted way, in
this case TX-ECHO can come after the response to the same TXed message.
In some cases, for example for J1939 stack, things will break.
This patch is using new rx-offload API to put the messages just in the
right place.

Marc Kleine-Budde 7da11ba5c5 can: dev: __can_get_echo_skb(): print error message, if trying to echo non existing skb
Prior to echoing a successfully transmitted CAN frame (by calling
can_get_echo_skb()), CAN drivers have to put the CAN frame (by calling
can_put_echo_skb() in the transmit function). These put and get function
take an index as parameter, which is used to identify the CAN frame.

A driver calling can_get_echo_skb() with a index not pointing to a skb
is a BUG, so add an appropriate error message.

The previous patch changes the TX path to always use the last mailbox
regardless of the used offload scheme (rx-fifo or timestamp based). This
means members "tx_mb" and "tx_mb_idx" of the struct flexcan_priv don't
depend on the offload scheme, so replace them by compile time constants.

Alexander Stein cbffaf7aa0 can: flexcan: Always use last mailbox for TX
Essentially this patch moves the TX mailbox to position 63, regardless
of timestamp based offloading or RX FIFO. So mainly the iflag register
usage regarding TX has changed. The rest is consolidating RX FIFO and
timestamp offloading as they now use both the same TX mailbox.

The reason is a very annoying behavior regarding sending RTR frames when
_not_ using RX FIFO:

If a TX mailbox sent a RTR frame it becomes a RX mailbox. For that
reason flexcan_irq disables the TX mailbox again. But if during the time
the RTR was sent and the TX mailbox is disabled a new CAN frames is
received, it is lost without notice. The reason is that so-called
"Move-in" process starts from the lowest mailbox which happen to be a TX
mailbox set to EMPTY.

Steps to reproduce (I used an imx7d):
1. generate regular bursts of messages
2. send a RTR from flexcan with higher priority than burst messages every
   1ms, e.g. cangen -I 0x100 -L 0 -g 1 -R can0
3. notice a lost message without notification after some seconds

When running an iperf in parallel this problem is occurring even more
frequently. Using filters is not possible as at least one single CAN-ID
is allowed. Handling the TX MB during RX is also not possible as there
is no race-free disable of RX MB.

There is still a slight window when the described problem can occur. But
for that all RX MB must be in use which is essentially next to an
overrun. Still there will be no indication if it ever occurs.

Lukas Wunner f164d0204b can: hi311x: Use level-triggered interrupt
If the hi3110 shares the SPI bus with another traffic-intensive device
and packets are received in high volume (by a separate machine sending
with "cangen -g 0 -i -x"), reception stops after a few minutes and the
counter in /proc/interrupts stops incrementing.  Bus state is "active".
Bringing the interface down and back up reconvenes the reception.  The
issue is not observed when the hi3110 is the sole device on the SPI bus.

Using a level-triggered interrupt makes the issue go away and lets the
hi3110 successfully receive 2 GByte over the course of 5 days while a
ks8851 Ethernet chip on the same SPI bus handles 6 GByte of traffic.

Unfortunately the hi3110 datasheet is mum on the trigger type.  The pin
description on page 3 only specifies the polarity (active high):

The assignment of the feature flag NETIF_F_NTUPLE and NETIF_F_HW_TC
occurs prior to the initial setup of the local hw_features variable.

This means the features are set as user-changeable, but are not set in
the currently active feature list. This results in the features being
disabled at the driver's initial load.

Move the assignment after the initial assignment of hw_features, and
assign to the local variable. This ensures that NETIF_F_NTUPLE and

Since commit bacd75cfac ("i40e/i40evf: Add capability exchange for
outer checksum", 2017-04-06) the i40e driver has not reported support
for IP-in-IP offloads. This likely occurred due to a bad rebase, as the
commit extracts hw_enc_features into its own variable. As part of this
change, it dropped the NETIF_F_FSO_IPXIP flags from the
netdev->hw_enc_features. This was unfortunately not caught during code
review.

Fix this by adding back the missing feature flags.

For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa

Miroslav Lichvar 4c9b658eea igb: shorten maximum PHC timecounter update interval
The timecounter needs to be updated at least once per ~550 seconds in
order to avoid a 40-bit SYSTIM timestamp to be misinterpreted as an old
timestamp.

Since commit 500462a9de ("timers: Switch to a non-cascading wheel"),
scheduling of delayed work seems to be less accurate and a requested
delay of 540 seconds may actually be longer than 550 seconds. Also, the
PHC may be adjusted to run up to 6% faster than real time and the system
clock up to 10% slower. Shorten the delay to 360 seconds to be sure the
timecounter is updated in time.

This fixes an issue with HW timestamps on 82580/I350/I354 being off by
~1100 seconds for few seconds every ~9 minutes.

netdev_tx_sent_queue will be incorrect. This is because in ice_tso we
overwrite the initial value that we set in ice_tx_map. This creates a
mismatch between the Tx and Tx clean flow. In the Tx clean flow we
calculate the bytecount (called total_bytes) as we clean the
descriptors so the value used in the Tx clean path is correct. Fix this
by using += in ice_tso instead of =. This fixes the mismatch in

Prior to this commit the driver was running into tx_timeouts when a
queue was stressed enough. This was happening because the HW tail
and SW tail (NTU) were incorrectly out of sync. Consequently this was
causing the HW head to collide with the HW tail, which to the hardware
means that all descriptors posted for Tx have been processed.

Due to the Tx logic used in the driver SW tail and HW tail are allowed
to be out of sync. This is done as an optimization because it allows the
driver to write HW tail as infrequently as possible, while still
updating the SW tail index to keep track. However, there are situations
where this results in the tail never getting updated, resulting in Tx
timeouts.

Tx HW tail write condition:
	if (netif_xmit_stopped(txring_txq(tx_ring) || !skb->xmit_more)
		writel(sw_tail, tx_ring->tail);

An issue was found in the Tx logic that was causing the afore mentioned
condition for updating HW tail to never happen, causing tx_timeouts.

In ice_xmit_frame_ring we calculate how many descriptors we need for the
Tx transaction based on the skb the kernel hands us. This is then passed
into ice_maybe_stop_tx along with some extra padding to determine if we
have enough descriptors available for this transaction. If we don't then
we return -EBUSY to the stack, otherwise we move on and eventually
prepare the Tx descriptors accordingly in ice_tx_map and set
next_to_watch. In ice_tx_map we make another call to ice_maybe_stop_tx
with a value of MAX_SKB_FRAGS + 4. The key here is that this value is
possibly less than the value we sent in the first call to
ice_maybe_stop_tx in ice_xmit_frame_ring. Now, if the number of unused
descriptors is between MAX_SKB_FRAGS + 4 and the value used in the first
call to ice_maybe_stop_tx in ice_xmit_frame_ring then we do not update
the HW tail because of the "Tx HW tail write condition" above. This is
because in ice_maybe_stop_tx we return success from ice_maybe_stop_tx
instead of calling __ice_maybe_stop_tx and subsequently calling
netif_stop_subqueue, which sets the __QUEUE_STATE_DEV_XOFF bit. This
bit is then checked in the "Tx HW tail write condition" by calling
netif_xmit_stopped and subsequently updating HW tail if the
afore mentioned bit is set.

In ice_clean_tx_irq, if next_to_watch is not NULL, we end up cleaning
the descriptors that HW sets the DD bit on and we have the budget. The
HW head will eventually run into the HW tail in response to the
description in the paragraph above.

The next time through ice_xmit_frame_ring we make the initial call to
ice_maybe_stop_tx with another skb from the stack. This time we do not
have enough descriptors available and we return NETDEV_TX_BUSY to the
stack and end up setting next_to_watch to NULL.

This is where we are stuck. In ice_clean_tx_irq we never clean anything
because next_to_watch is always NULL and in ice_xmit_frame_ring we never
update HW tail because we already return NETDEV_TX_BUSY to the stack and
eventually we hit a tx_timeout.

This issue was fixed by making sure that the second call to
ice_maybe_stop_tx in ice_tx_map is passed a value that is >= the value
that was used on the initial call to ice_maybe_stop_tx in
ice_xmit_frame_ring. This was done by adding the following defines to
make the logic more clear and to reduce the chance of mucking this up
again:

ICE_CACHE_LINE_BYTES		64
ICE_DESCS_PER_CACHE_LINE	(ICE_CACHE_LINE_BYTES / \
				 sizeof(struct ice_tx_desc))
ICE_DESCS_FOR_CTX_DESC		1
ICE_DESCS_FOR_SKB_DATA_PTR	1

The ICE_CACHE_LINE_BYTES being 64 is an assumption being made so we
don't have to figure this out on every pass through the Tx path. Instead
I added a sanity check in ice_probe to verify cache line size and print
a message if it's not 64 Bytes. This will make it easier to file issues
if they are seen when the cache line size is not 64 Bytes when reading
from the GLPCI_CNF2 register.

Tao Ren 042cb56478 net: phy: Allow BCM54616S PHY to setup internal TX/RX clock delay
This patch allows users to enable/disable internal TX and/or RX clock
delay for BCM54616S PHYs so as to satisfy RGMII timing specifications.

On a particular platform, whether TX and/or RX clock delay is required
depends on how PHY connected to the MAC IP. This requirement can be
specified through "phy-mode" property in the platform device tree.

The patch is inspired by commit 733336262b ("net: phy: Allow BCM5481x

Arnd Bergmann b374e8686f mt76: fix building without CONFIG_LEDS_CLASS

We don't really need a hard dependency here as the driver can presumably
work just fine without LEDs, so this follows the iwlwifi example and
adds a separate Kconfig option for the LED support, this will be available
whenever it will link, and otherwise the respective code gets left out from
the driver object.

It seems since we don't have a wakeirq value in the dts, the wakeirq
value in wl1271_probe() is zero, which then causes trouble in
irqd_get_trigger_type(irq_get_irq_data(wakeirq)).

This patch tries to address this by checking if wakeirq is zero,
and not trying to add it to the resources if that is the case.

Jarod Wilson ea53abfab9 bonding/802.3ad: fix link_failure_count tracking
Commit 4d2c0cda07 set slave->link to
BOND_LINK_DOWN for 802.3ad bonds whenever invalid speed/duplex values
were read, to fix a problem with slaves getting into weird states, but
in the process, broke tracking of link failures, as going straight to
BOND_LINK_DOWN when a link is indeed down (cable pulled, switch rebooted)
means we broke out of bond_miimon_inspect()'s BOND_LINK_DOWN case because
!link_state was already true, we never incremented commit, and never got
a chance to call bond_miimon_commit(), where slave->link_failure_count
would be incremented. I believe the simple fix here is to mark the slave
as BOND_LINK_FAIL, and let bond_miimon_inspect() transition the link from
_FAIL to either _UP or _DOWN, and in the latter case, we now get proper
incrementing of link_failure_count again.

Florian Fainelli 7cb6a2a2c7 net: systemport: Protect stop from timeout
A timing hazard exists when the network interface is stopped that
allows a watchdog timeout to be processed by a separate core in
parallel. This creates the potential for the timeout handler to
wake the queues while the driver is shutting down, or access
registers after their clocks have been removed.

The more common case is that the watchdog timeout will produce a
warning message which doesn't lead to a crash. The chances of this
are greatly increased by the fact that bcm_sysport_netif_stop stops
the transmit queues which can easily precipitate a watchdog time-
out because of stale trans_start data in the queues.

This commit corrects the behavior by ensuring that the watchdog
timeout is disabled before enterring bcm_sysport_netif_stop. There
are currently only two users of the bcm_sysport_netif_stop function:
close and suspend.

The close case already handles the issue by exiting the RUNNING
state before invoking the driver close service.

The suspend case now performs the netif_device_detach to exit the
PRESENT state before the call to bcm_sysport_netif_stop rather than
after it.

These behaviors prevent any future scheduling of the driver timeout
service during the window. The netif_tx_stop_all_queues function
in bcm_sysport_netif_stop is replaced with netif_tx_disable to ensure
synchronization with any transmit or timeout threads that may
already be executing on other cores.

For symmetry, the netif_device_attach call upon resume is moved to
after the call to bcm_sysport_netif_start. Since it wakes the transmit
queues it is not necessary to invoke netif_tx_start_all_queues from
bcm_sysport_netif_start so it is moved into the driver open service.

Niklas Cassel 30549aab14 net: stmmac: Fix stmmac_mdio_reset() when building stmmac as modules
When building stmmac, it is only possible to select CONFIG_DWMAC_GENERIC,
or any of the glue drivers, when CONFIG_STMMAC_PLATFORM is set.
The only exception is CONFIG_STMMAC_PCI.

When calling of_mdiobus_register(), it will call our ->reset()
callback, which is set to stmmac_mdio_reset().

Most of the code in stmmac_mdio_reset() is protected by a
"#if defined(CONFIG_STMMAC_PLATFORM)", which will evaluate
to false when CONFIG_STMMAC_PLATFORM=m.

Because of this, the phy reset gpio will only be pulled when
stmmac is built as built-in, but not when built as modules.

Fix this by using "#if IS_ENABLED()" instead of "#if defined()".

Intel Wired LAN Driver Updates 2018-10-31

This series contains a various collection of fixes.

Miroslav Lichvar from Red Hat or should I say IBM now?  Updates the PHC
timecounter interval for igb so that it gets updated at least once
every 550 seconds.

Ngai-Mint provides a fix for fm10k to prevent a soft lockup or system
crash by adding a new condition to determine if the SM mailbox is in the
correct state before proceeding.

Jake provides several fm10k fixes, first one marks complier aborts as
non-fatal since on some platforms trigger machine check errors when the
compile aborts.  Added missing device ids to the in-kernel driver.  Due
to the recent fixes, bumped the driver version.

I (Jeff Kirsher) fixed a XFRM_ALGO dependency for both ixgbe and
ixgbevf.  This fix was based on the original work from Arnd Bergmann,
which only fixed ixgbe.

Mitch provides a fix for i40e/avf to update the status codes, which
resolves an issue between a mis-match between i40e and the iavf driver,
which also supports the ice LAN driver.

Radoslaw fixes the ixgbe where the driver is logging a message about
spoofed packets detected when the VF is re-started with a different MAC
address.

Petr Machata 0fe6402316 mlxsw: spectrum: Set minimum shaper on MC TCs
An MC-aware mode was introduced in commit 7b81953066 ("mlxsw:
spectrum: Configure MC-aware mode on mlxsw ports"). In MC-aware mode,
BUM traffic gets a special treatment by being assigned to a separate set
of traffic classes 8..15. Pairs of TCs 0 and 8, 1 and 9, etc., are then
configured to strictly prioritize the lower-numbered ones. The intention
is to prevent BUM traffic from flooding the switch and push out all UC
traffic, which would otherwise happen, and instead give UC traffic
precedence.

However strictly prioritizing UC traffic has the effect that UC overload
pushes out all BUM traffic, such as legitimate ARP queries. These
packets are kept in queues for a while, but under sustained UC overload,
their lifetime eventually expires and these packets are dropped. That is
detrimental to network performance as well.

Therefore configure the MC TCs (8..15) with minimum shaper of 200Mbps (a
minimum permitted value) to allow a trickle of necessary control traffic
to get through.

When there is a PHY, the driver needs to complete some operations through
MDIO during reset reinitialization, so HCLGE_STATE_CMD_DISABLE is more
suitable than HCLGE_STATE_RST_HANDLING to prevent the MDIO operation from

Eric Dumazet d48051c5b8 net/mlx5e: fix csum adjustments caused by RXFCS
As shown by Dmitris, we need to use csum_block_add() instead of csum_add()
when adding the FCS contribution to skb csum.

Before 4.18 (more exactly commit 88078d98d1 "net: pskb_trim_rcsum()
and CHECKSUM_COMPLETE are friends"), the whole skb csum was thrown away,
so RXFCS changes were ignored.

Then before commit d55bef5059 ("net: fix pskb_trim_rcsum_slow() with
odd trim offset") both mlx5 and pskb_trim_rcsum_slow() bugs were canceling
each other.

Now we fixed pskb_trim_rcsum_slow() we need to fix mlx5.

Note that this patch also rewrites mlx5e_get_fcs() to :

- Use skb_header_pointer() instead of reinventing it.
- Use __get_unaligned_cpu32() to avoid possible non aligned accesses
  as Dmitris pointed out.

Jeff Kirsher 48e01e001d ixgbe/ixgbevf: fix XFRM_ALGO dependency
Based on the original work from Arnd Bergmann.

When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a
link error:

drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa':
ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname'

Simply selecting XFRM_ALGO from here causes circular dependencies, so
to fix it, we probably want this slightly more complex solution that is
similar to what other drivers with XFRM offload do:

A separate Kconfig symbol now controls whether we include the IPsec
offload code. To keep the old behavior, this is left as 'default y'. The
dependency in XFRM_OFFLOAD still causes a circular dependency but is
not actually needed because this symbol is not user visible, so removing
that dependency on top makes it all work.

Jacob Keller e330af7889 fm10k: ensure completer aborts are marked as non-fatal after a resume
VF drivers can trigger PCIe completer aborts any time they read a queue
that they don't own. Even in nominal circumstances, it is not possible
to prevent the VF driver from reading queues it doesn't own. VF drivers
may attempt to read queues it previously owned, but which it no longer
does due to a PF reset.

Normally these completer aborts aren't an issue. However, on some
platforms these trigger machine check errors. This is true even if we
lower their severity from fatal to non-fatal. Indeed, we already have
code for lowering the severity.

We could attempt to mask these errors conditionally around resets, which
is the most common time they would occur. However this would essentially
be a race between the PF and VF drivers, and we may still occasionally
see machine check exceptions on these strictly configured platforms.

Instead, mask the errors entirely any time we resume VFs. By doing so,
we prevent the completer aborts from being sent to the parent PCIe
device, and thus these strict platforms will not upgrade them into
machine check errors.

Additionally, we don't lose any information by masking these errors,
because we'll still report VFs which attempt to access queues via the
FUM_BAD_VF_QACCESS errors.

Without this change, on platforms where completer aborts cause machine
check exceptions, the VF reading queues it doesn't own could crash the
host system. Masking the completer abort prevents this, so we should
mask it for good, and not just around a PCIe reset. Otherwise malicious
or misconfigured VFs could cause the host system to crash.

Because we are masking the error entirely, there is little reason to
also keep setting the severity bit, so that code is also removed.

Ngai-Mint Kwan e69e40c806 fm10k: fix SM mailbox full condition
Current condition will always incorrectly report a full SM mailbox if an
IES API application is not running. Due to this, the
"fm10k_service_task" will be infinitely queued into the driver's
workqueue. This, in turn, will cause a "kworker" thread to report 100%
CPU utilization and might cause "soft lockup" events or system crashes.

To fix this issue, a new condition is added to determine if the SM
mailbox is in the correct state of FM10K_STATE_OPEN before proceeding.
In other words, an instance of the IES API must be running. If there is,
the remainder of the flow stays the same which is to determine if the SM
mailbox capacity has been exceeded or not and take appropriate action.

Miroslav Lichvar 094bf4d0e9 igb: shorten maximum PHC timecounter update interval
The timecounter needs to be updated at least once per ~550 seconds in
order to avoid a 40-bit SYSTIM timestamp to be misinterpreted as an old
timestamp.

Since commit 500462a9d ("timers: Switch to a non-cascading wheel"),
scheduling of delayed work seems to be less accurate and a requested
delay of 540 seconds may actually be longer than 550 seconds. Shorten
the delay to 480 seconds to be sure the timecounter is updated in time.

This fixes an issue with HW timestamps on 82580/I350/I354 being off by
~1100 seconds for few seconds every ~9 minutes.

Sabrina Dubroca e6ac075882 macsec: update operstate when lower device changes
Like all other virtual devices (macvlan, vlan), the operstate of a
macsec device should match the state of its lower device. This is done
by calling netif_stacked_transfer_operstate from its netdevice notifier.

We also need to call netif_stacked_transfer_operstate when a new macsec
device is created, so that its operstate is set properly. This is only
relevant when we try to bring the device up directly when we create it.

Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
that included changing the administrative state of the macsec device,
instead of just the operstate. This version is similar to what the
macvlan driver does, and updates only the operstate.

Heiner Kallweit 649f0837a8 r8169: fix broken Wake-on-LAN from S5 (poweroff)
It was reported that WoL from S5 is broken (WoL from S3 works) and the
analysis showed that during system shutdown the network interface was
brought down already when the actual kernel shutdown started.
Therefore netif_running() returned false and as a consequence the PHY
was suspended. Obviously WoL wasn't working then.
To fix this the original patch needs to be effectively reverted.
A side effect is that when normally bringing down the interface and
WoL is enabled the PHY will remain powered on (like it was before the
original patch).

====================
Intel Wired LAN Driver Fixes 2018-10-24

This series contains fixes for the ice driver.

Anirudh fixes a namespace issue which was introduced with a previous
patch to remove ice_netpoll.  Fixed up the device ID define names to
align with the branding string names.  Use the capability count returned
by the firmware, instead of calculating the count.  Introduced driver
workarounds due to current firmware limitations.  Fixed the queue
mapping for a VF, which needs to be set in the config and scatter queue
modes.  Fixed the driver which is setup to handle link status events
(LSE), even though the firmware does not have this feature yet, so add
the ability to poll for link status changes while we wait for updated
firmware.

Anirudh Venkataramanan 4f4be03bde ice: Poll for link status change
When the physical link goes up or down, the driver is supposed to
receive a link status event (LSE). The driver currently has the code
to handle LSEs but there is no firmware support for this feature yet.
So this patch adds the ability for the driver to poll for link status
changes. The polling itself is done in ice_watchdog_subtask.

For namespace cleanliness, this patch also removes code that handles
LSE. This code will be reintroduced once the feature is officially
supported.

Allocate VF interrupts using VPINT_ALLOC_PCI. Multiple interrupts are
specified as a range from "first" to "last".

Also, according to the spec, the queue mapping for a VF needs to be set
in both contig and scatter queue modes. So make this change as well.

Anirudh Venkataramanan f203dca363 ice: Introduce ice_dev_onetime_setup
ice_dev_onetime_setup contains a couple of driver workarounds for current
firmware limitations. These workarounds are expected to go away once
these limitations are fixed in the firmware.

On a firmware release that has these issues addressed, these workarounds
(while unnecessary) will not break anything.

Pull tty ioctl updates from Al Viro:
 "This is the compat_ioctl work related to tty ioctls.

  Quite a bit of dead code taken out, all tty-related stuff gone from
  fs/compat_ioctl.c. A bunch of compat bugs fixed - some still remain,
  but all more or less generic tty-related ioctls should be covered
  (remaining issues are in things like driver-private ioctls in a pcmcia
  serial card driver not getting properly handled in 32bit processes on
  64bit host, etc)"

Johan Hovold ac63043d8c net: stmmac: dwmac-sun8i: fix OF child-node lookup
Use the new of_get_compatible_child() helper to lookup the mdio-internal
child node instead of using of_find_compatible_node(), which searches
the entire tree from a given start node and thus can return an unrelated
(i.e. non-child) node.

This also addresses a potential use-after-free (e.g. after probe
deferral) as the tree-wide helper drops a reference to its first
argument (i.e. the mdio-mux node). Fortunately, this was inadvertently
balanced by a failure to drop the mdio-mux reference after lookup.

While at it, also fix the related mdio-internal- and phy-node reference
leaks.
