Commit 2b30842b23b9 ("net: fec: Clear and enable MIB counters on imx51")
introduced fec_enet_clear_ethtool_stats(), but missed to add a stub
for the CONFIG_M5272=y case, causing build failure for the
m5272c3_defconfig.
Add the missing empty stub to fix the build failure.

Once firmware indicates that a given VF is malicious and until
that VF passes an FLR all bets are off - PF can't know anything
is happening to the VF [since VF can't communicate anything to its PF].
But PF is currently still periodically asking device to collect
statistics for the VF which might in turn fill logs by IOMMU blocking
memory access done by the VF's PCI function [in the case VF has unmapped
its buffers].

VF clients are configured as enforced, meaning firmware is validating
the correctness of their ethertype/vid during transmission.
Once txvlan is disabled, VF would start getting SKBs for transmission
here vlan is on the payload - but it'll pass the packet's ethertype
instead of the vid, leading to firmware declaring it as malicious.

CAN FD capable CAN interfaces can handle (classic) CAN 2.0 frames too.
New users usually fail at their first attempt to explore CAN FD on
virtual CAN interfaces due to the current CAN_MTU default.
Set the MTU to CANFD_MTU by default to reduce this confusion.
If someone *really* needs a 'classic CAN'-only device this can be set
with the 'ip' tool with e.g. 'ip link set vcan0 mtu 16' as before.

In OOM situations where no skb can be allocated, can_change_state() may
be called with cf == NULL. As this function updates the state and error
statistics it's not an option to skip the call to can_change_state() in
OOM situations.
This patch makes can_change_state() robust, so that it can be called
with cf == NULL.

Commit 1aa6c4f6b8cd8 ("net: vrf: Add l3mdev rules on first device create")
adds the l3mdev FIB rule the first time a VRF device is created. However,
it only creates the rule once and only in the namespace the first device
is created - which may not be init_net. Fix by using the net_generic
capability to make the add_fib_rules flag per network namespace.

emac_mdio_read_link() was not copying the requested phy settings
back into the emac driver's own phy api. This has caused a link
speed mismatch issue for the AR8035 as the emac driver kept
trying to connect with 10/100MBps on a 1GBit/s link.
This patch also unifies shared code between emac_setup_aneg()
and emac_mdio_setup_forced(). And furthermore it removes
a chunk of emac_mdio_init_phy(), that was copying the same
data into itself.

This patch fixes a problem where the AR8035 PHY can't be
detected on an Cisco Meraki MR24, if the ethernet cable is
not connected on boot.
Russell Senior provided steps to reproduce the issue:
|Disconnect ethernet cable, apply power, wait until device has booted,
|plug in ethernet, check for interfaces, no eth0 is listed.
|
|This appears to be a problem during probing of the AR8035 Phy chip.
|When ethernet has no link, the phy detection fails, and eth0 is not
|created. Plugging ethernet later has no effect, because there is no
|interface as far as the kernel is concerned. The relevant part of
|the boot log looks like this:
|this is the failing case:
|
|[ 0.876611] /plb/opb/emac-rgmii@ef601500: input 0 in RGMII mode
|[ 0.882532] /plb/opb/ethernet@ef600c00: reset timeout
|[ 0.888546] /plb/opb/ethernet@ef600c00: can't find PHY!
|and the succeeding case:
|
|[ 0.876672] /plb/opb/emac-rgmii@ef601500: input 0 in RGMII mode
|[ 0.883952] eth0: EMAC-0 /plb/opb/ethernet@ef600c00, MAC 00:01:..
|[ 0.890822] eth0: found Atheros 8035 Gigabit Ethernet PHY (0x01)
Based on the comment and the commit message of
commit 23fbb5a87c56 ("emac: Fix EMAC soft reset on 460EX/GT").
This is because the AR8035 PHY doesn't provide the TX Clock,
if the ethernet cable is not attached. This causes the reset
to timeout and the PHY detection code in emac_init_phy() is
unable to detect the AR8035 PHY. As a result, the emac driver
bails out early and the user left with no ethernet.
In order to stay compatible with existing configurations, the driver
tries the current reset approach at first. Only if the first attempt
timed out, it does perform one more retry with the clock temporarily
switched to the internal source for just the duration of the reset.

Network devices can allocate reasources and private memory using
netdev_ops->ndo_init(). However, the release of these resources
can occur in one of two different places.
Either netdev_ops->ndo_uninit() or netdev->destructor().
The decision of which operation frees the resources depends upon
whether it is necessary for all netdev refs to be released before it
is safe to perform the freeing.
netdev_ops->ndo_uninit() presumably can occur right after the
NETDEV_UNREGISTER notifier completes and the unicast and multicast
address lists are flushed.
netdev->destructor(), on the other hand, does not run until the
netdev references all go away.
Further complicating the situation is that netdev->destructor()
almost universally does also a free_netdev().
This creates a problem for the logic in register_netdevice().
Because all callers of register_netdevice() manage the freeing
of the netdev, and invoke free_netdev(dev) if register_netdevice()
fails.
If netdev_ops->ndo_init() succeeds, but something else fails inside
of register_netdevice(), it does call ndo_ops->ndo_uninit(). But
it is not able to invoke netdev->destructor().
This is because netdev->destructor() will do a free_netdev() and
then the caller of register_netdevice() will do the same.
However, this means that the resources that would normally be released
by netdev->destructor() will not be.
Over the years drivers have added local hacks to deal with this, by
invoking their destructor parts by hand when register_netdevice()
fails.
Many drivers do not try to deal with this, and instead we have leaks.
Let's close this hole by formalizing the distinction between what
private things need to be freed up by netdev->destructor() and whether
the driver needs unregister_netdevice() to perform the free_netdev().
netdev->priv_destructor() performs all actions to free up the private
resources that used to be freed by netdev->destructor(), except for
free_netdev().
netdev->needs_free_netdev is a boolean that indicates whether
free_netdev() should be done at the end of unregister_netdevice().
Now, register_netdevice() can sanely release all resources after
ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit()
and netdev->priv_destructor().
And at the end of unregister_netdevice(), we invoke
netdev->priv_destructor() and optionally call free_netdev().

stmmac_tso_allocator can fail to set the Last Descriptor bit
on a descriptor that actually was the last descriptor.
This happens when the buffer of the last descriptor ends
up having a size of exactly TSO_MAX_BUFF_SIZE.
When the IP eventually reaches the next last descriptor,
which actually has the bit set, the DMA will hang.
When the DMA hangs, we get a tx timeout, however,
since stmmac does not do a complete reset of the IP
in stmmac_tx_timeout, we end up in a state with
completely hung TX.

Commit a47b70ea86bd ("ravb: unmap descriptors when freeing rings") has
introduced the issue seen in [1] reproduced on H3ULCB board.
Fix this by relocating the RX skb ringbuffer free operation, so that
swiotlb page unmapping can be done first. Freeing of aligned TX buffers
is not relevant to the issue seen in [1]. Still, reposition TX free
calls as well, to have all kfree() operations performed consistently
_after_ dma_unmap_*()/dma_free_*().

The current comparison of entry < 0 will never be true since entry is an
unsigned integer. Make entry an int to ensure -ve error return values
from the call to jumbo_frm are correctly being caught.

Pull media fixes from Mauro Carvalho Chehab:
"Some bug fixes:
- Don't fail build if atomisp has warnings
- Some CEC Kconfig changes to allow it to be used by DRM without
media dependencies
- A race fix at RC initialization code
- A driver fix at rainshadow-cec
IMHO, the one that affects most people in this series is a build fix:
if you try to build the Kernel with W=1 or using gcc7 and
all[yes|mod]config, build will fail due to -Werror at atomisp
makefiles"

In f8b45b74cc62 ("i40e/i40evf: Use build_skb to build frames")
i40e_build_skb updates the page_offset field with an incorrect offset,
which can lead to data corruption. This patch updates page_offset
correctly, by properly setting truesize.
Note that the bug only appears on architectures where PAGE_SIZE is
8192 or larger.

Commit 0da36b9774cc ("i40e: use DECLARE_BITMAP for state fields")
introduced changes in the way i40e works with state flags converting
them to bitmaps using kernel bitmap API. This change introduced a
regression due to a mistaken substitution using __I40E_VSI_DOWN instead
of __I40E_DOWN when testing state of a PF at i40e_reset_subtask()
function. This caused a flood in the kernel log with the follow message:
[49.013] i40e 0002:01:00.0: bad reset request 0x00000020
Commit d19cb64b9222 ("i40e: separate PF and VSI state flags")
also introduced some misuse of the VSI and PF flags, so both could be
considered as the offenders.
This patch simply fixes the flags where it makes sense by changing
__I40E_VSI_DOWN to __I40E_DOWN.

The iwl_mvm_remove_sta_key() function handles removing a key when the
sta doesn't exist anymore. Mistakenly, this was changed to return an
error while fixing another bug.
If the mvm_sta doesn't exist, we continue normally, but just don't try
to remove the igtk key.

system_pm is set to IWL_PLAT_PM_MODE_D0I3, otherwise d0i3 entry
failures will cause suspend to fail.

When we want to stop the recording of the firmware debug
and restart it later without reloading the firmware we
don't need to resend the configuration that comes with
host commands.
Sending those commands confused the hardware and led to
an NMI 0x66.
Change the flow as following:
* read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL)
* clear those registers
* wait for the hardware to complete its write to the buffer
* get the data
* restore the value of those registers (to restart the
recording)
For early start (where the configuration is already
compiled in the firmware), we don't need to set those
registers after the firmware has been loaded, but only
when we want to restart the recording without having
restarted the firmware.
