FW/HW can generally support the standard networking offloads
on representors without any trouble. Add the ability for FW
to advertise which features should be available on representors.
Because representors are muxed on top of the vNIC we need to listen
on feature changes of their lower devices, and update their features
appropriately.

Up until now we never needed to keep a networking locks around
representors accesses, we only accessed them when device was
reconfigured (under nfp pf->lock) or on fast path (under RCU).
Now we want to be able to iterate over all representors during
notifications, so make sure representor assignment is done
under RTNL lock.

Chained descriptors for fragments need to duplicate all the descriptor

Previously when unbinding a slave the 802.3ad implementation only told
partner that the port is not suitable for aggregation by setting the port
aggregation state from aggregatable to individual. This is not enough. If the
physical layer still stays up and we only unbinded this port from the bond there
is nothing in the aggregation status alone to prevent the partner from sending
traffic towards us. To ensure that the partner doesn't consider this
port at all anymore we should also disable collecting and distributing to
signal that this actor is going away. Also clear AD_STATE_SYNCHRONIZATION to
ensure partner exits collecting + distributing state.
I have tested this behaviour againts Arista EOS switches with mlx5 cards
(physical link stays up even when interface is down) and simulated
the same situation virtually Linux <-> Linux with two network namespaces
running two veth device pairs. In both cases setting aggregation to
individual doesn't alone prevent traffic from being to sent towards this
port given that the link stays up in partners end. Partner still keeps
it's end in collecting + distributing state and continues until timeout is
reached. In most cases this means we are losing the traffic partner sends
towards our port while we wait for timeout. This is most visible with slow
periodic time (LACP rate slow).
Other open source implementations like Open VSwitch and libreswitch, and
vendor implementations like Arista EOS, seem to disable collecting +
distributing to when doing similar port disabling/detaching/removing change.
With this patch kernel implementation would behave the same way and ensure
partner doesn't consider our actor viable anymore.

Setting up and tearing down debugfs is current unbalanced, as seen by
this error during resume from suspend:
[ 752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory
[ 752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration
The imbalance happens because the driver creates the debugfs hierarchy
when the device is opened and tears it down when the device is closed.
There's little gain in that, and it could be argued that it is even
surprising because it's not usually done for other devices. Fix the
imbalance by moving the debugfs creation and teardown to the driver's
->probe() and ->remove() implementations instead.
Note that the ring descriptors cannot be read while the interface is
down, so make sure to return an empty file when the descriptors_status
debugfs file is read.

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.

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.

Marc Kleine-Budde says:
====================
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.

Trivial conflict in net/core/filter.c, a locally computed
'sdif' is now an argument to the function.

====================
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.
