Commit 1c30d1836aeb ("mlxsw: spectrum: Enable VxLAN enslavement to
bridges") enabled the enslavement of VxLAN devices to bridges that have
mlxsw ports (or their upper) as slaves. This patch extends mlxsw to also
support VLAN-aware bridges.
The patch is similar in nature to mentioned commit, but there is one
major difference. With VLAN-aware bridges, the VxLAN device's VNI is
mapped to the VLAN that is configured as PVID and egress untagged on the
bridge port.
Therefore, the driver is extended to listen to VLAN configuration on
VxLAN devices of interest and enable / disable NVE encapsulation on the
corresponding 802.1Q FIDs.
To prevent ambiguity, the driver makes sure that a given VLAN is not
configured as PVID and egress untagged on multiple VxLAN devices. This
sanitization takes place both when a port is enslaved to a bridge with
existing VxLAN devices and when a VLAN is added to / removed from a
VxLAN device of interest.

The vxlan_join() function resolves the FID on which the VNI should be
set and then sets the VNI. Currently, the FID is simply resolved
according to the ifindex of the bridge device to which the VxLAN device
is enslaved. This works because only VLAN-unaware bridges are supported.
With VLAN-aware bridges the FID would need to be resolved based on the
VLAN to which the VNI is mapped to.
Add the VLAN ID to the argument list of the function.

The function mlxsw_sp_bridge_vxlan_leave() is currently split between
VLAN-aware and VLAN-unaware bridges, but actually both types can use the
same function.
The function needs to resolve the FID that corresponds to the VxLAN
device and disable NVE encapsulation on it. Instead of looking up the
FID differently for VLAN-aware and VLAN-unaware bridges, we can always
use the VxLAN's device VNI.

In a similar fashion to commit 564c6d727aca ("mlxsw: spectrum_fid: Add
APIs to lookup FID without creating it"), add a corresponding API to
lookup 802.1Q FIDs.
This is a prerequisite to VxLAN support with VLAN-aware bridges and will
allow us to resolve a 802.1Q FID by its VLAN when an FDB entry is added
on the bridge port of the VxLAN device.

If wol state of phy hardware is enabled after reset, phy_ethtool_get_wol()
returns that wol.wolopts is true.
However, since net_device.wol_enabled is zero and this doesn't apply wol
state until calling ethtool_set_wol(), so mdio_bus_phy_may_suspend()
returns true, that is, it's in a state where phy can suspend even though
wol state is enabled.
In this inconsistency, phy_suspend() returns -EBUSY, and at last,
suspend sequence fails with the following message:
dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x58 returns -16
PM: Device 65000000.ethernet-ffffffff:01 failed to suspend: error -16
PM: Some devices failed to suspend, or early wake event detected
In order to fix the above issue, this patch forces to set initial wol state
to disabled as default.

[ 31.096533] Disabling lock debugging due to kernel taint
It appears that when trying to determine the length of the string in the
alternate firmware path, we make the mistake of not handling the case
where the firmware path is empty correctly. Since strlen(mp_path) can
return 0, we'll end up accessing mp_path[-1] when the firmware_path
isn't provided through the module arguments.
So, fix this by just setting the end char to '\0' by default, and only
changing it if we have a non-zero length. Additionally, use strnlen()
with BRCMF_FW_ALTPATH_LEN instead of strlen() just to be extra safe.

ARM systems with UEFI may have both devicetree (of) and DMI data in this
case we end up setting brcmf_mp_device.board_type twice.
In this case we should prefer the devicetree data, because:
1) The devicerree data is more reliable
2) Some ARM systems (e.g. the Raspberry Pi 3 models) support both UEFI and
classic uboot booting, the devicetree data is always there, so using it
makes sure we ask for the same nvram file independent of how we booted.
This commit moves the brcmf_dmi_probe call to before the brcmf_of_probe
call, so that the latter can override the value of the first if both are
set.

The newest firmwares provide STA info using v7 of the struct. As v7
isn't backward compatible, a union is needed.

====================
This is a pull request for net-next/master consisting of 18 patches.
The first patch is by Colin Ian King and fixes the spelling in the ucan
driver.
The next three patches target the xilinx driver. YueHaibing's patch
fixes the return type of ndo_start_xmit function. Two patches by
Shubhrajyoti Datta add support for the CAN FD 2.0 controllers.
Flavio Suligoi's patch for the sja1000 driver add support for the ASEM
CAN raw hardware.
Wolfram Sang's and Kuninori Morimoto's patches switch the rcar driver to
use SPDX license identifiers.
The remaining 111 patches improve the flexcan driver. Pankaj Bansal's
patch enables the driver in Kconfig on all architectures with IOMEM
support. The next four patches by me fix indention, add missing
parentheses and comments. Aisheng Dong's patches add self wake support
and document it in the DT bindings. The remaining patches by Pankaj
Bansal first fix the loopback support and prepare the driver for the
CAN-FD support needed for the LX2160A SoC. The actual CAN-FD support
will be added in a later patch series.

====================
Intel Wired LAN Driver Fixes 2018-11-28
This series contains fixes to igb, ixgbe and i40e.
Yunjian Wang from Huawei resolves a variable that could potentially be
NULL before it is used.
Lihong fixes an i40e issue which goes back to 4.17 kernels, where
deleting any of the MAC filters was causing the incorrect syncing for
the PF.
Josh Elsasser caught that there were missing enum values in the link
capabilities for x550 devices, which was preventing link for 1000BaseLX
SFP modules.
Jan fixes the function header comments for XSK methods.

The response for a SNMP request can consist of multiple parts, which
the cmd callback stages into a kernel buffer until all parts have been
received. If the callback detects that the staging buffer provides
insufficient space, it bails out with error.
This processing is buggy for the first part of the response - while it
initially checks for a length of 'data_len', it later copies an
additional amount of 'offsetof(struct qeth_snmp_cmd, data)' bytes.
Fix the calculation of 'data_len' for the first part of the response.
This also nicely cleans up the memcpy code.

Send frames back on the same port for XDP_TX action.
Since the frame buffers have been allocated by us, we can recycle
them directly into the Rx buffer pool instead of requesting a
confirmation frame upon transmission complete.

Instead of freeing the RX buffers, release them back into the pool.
We wait for the maximum number of buffers supported by a single
release command to accumulate before issuing the command.
Also, don't unmap the Rx buffers at the beginning of the Rx routine
anymore, since that would require remapping them before release.
Instead, just do a DMA sync at first and only unmap if the frame is
meant for the stack.

We'll use function free_bufs() on the XDP path as well, so move
it higher in order to avoid a forward declaration.
