08f588fa30 devlink: introduce framework for selftests
Add a framework for running selftests.
Framework exposes devlink commands and test suite(s) to the user

Below are new entries in devlink_nl_ops
devlink_nl_cmd_selftests_show_doit/dumpit: To query the supported
selftests by the drivers.
devlink_nl_cmd_selftests_run: To execute selftests. Users can
provide a test mask for executing group tests or standalone tests.

aa709da0e0 Documentation: fix sctp_wmem in ip-sysctl.rst
Since commit 1033990ac5 ("sctp: implement memory accounting on tx path"),
SCTP has supported memory accounting on tx path where 'sctp_wmem' is used
by sk_wmem_schedule(). So we should fix the description for this option in
ip-sysctl.rst accordingly.

v1->v2:
  - Improve the description as Marcelo suggested.

6ba1a4aa59 docs: net: dsa: delete misinformation about -EOPNOTSUPP for FDB/MDB/VLAN
Returning -EOPNOTSUPP does *NOT* mean anything special.

port_vlan_add() is actually called from 2 code paths, one is
vlan_vid_add() from 8021q module and the other is
br_switchdev_port_vlan_add() from switchdev.

The bridge has a wrapper __vlan_vid_add() which first tries via
switchdev, then if that returns -EOPNOTSUPP, tries again via the VLAN RX
filters in the 8021q module. But DSA doesn't distinguish between one
call path and the other when calling the driver's port_vlan_add(), so if
the driver returns -EOPNOTSUPP to switchdev, it also returns -EOPNOTSUPP
to the 8021q module. And the latter is a hard error.

port_fdb_add() is called from the deferred dsa_owq only, so obviously
its return code isn't propagated anywhere, and cannot be interpreted in
any way.

The return code from port_mdb_add() is propagated to the bridge, but
again, this doesn't do anything special when -EOPNOTSUPP is returned,
but rather, br_switchdev_mdb_notify() returns void.

- SMCR_VIRT_CONT_BUFS, which means use virtually contiguous
  buffers in case of physically contiguous memory is scarce.

f05643a0f6 eth: remove neterion/vxge
The last meaningful change to this driver was made by Jon in 2011.
As much as we'd like to believe that this is because the code is
perfect the chances are nobody is using this hardware.

Because of the size of this driver there is a nontrivial maintenance
cost to keeping this code around, in the last 2 years we're averaging
more than 1 change a month. Some of which require nontrivial review
effort, see commit 877fe9d49b ("Revert "drivers/net/ethernet/neterion/vxge:
Fix a use-after-free bug in vxge-main.c"") for example.

Let's try to remove this driver. In general, IMHO, we need to
establish a clear path for shedding dead code. It will be hard
to unless we have some experience trying to delete stuff.

====================
pull-request: can-next 2022-07-03

this is a pull request of 15 patches for net-next/master.

The first 2 patches are by Max Staudt and add the can327 serial CAN
driver along with a new line discipline ID.

The next patch is by me an fixes a typo in the ctucanfd driver.

The last 12 patches are by Dario Binacchi and integrate slcan CAN
serial driver better into the existing CAN driver API.

system work queue hog CPU to 100%, and further more we should introduce

43da2f0762 can: can327: CAN/ldisc driver for ELM327 based OBD-II adapters
This is the can327 driver. It does a surprisingly good job at turning
ELM327 based OBD-II interfaces into cheap CAN interfaces for simple
homebrew projects.

Please see the included documentation for details and limitations:
Documentation/networking/device_drivers/can/can327.rst

====================
pull-request: can-next 2022-06-25

this is a pull request of 22 patches for net-next/master.

The first 2 patches target the xilinx driver. Srinivas Neeli's patch
adds Transmitter Delay Compensation (TDC) support, a patch by me fixes
a typo.

The next patch is by me and fixes a typo in the m_can driver.

Another patch by me allows the configuration of fixed bit rates
without need for do_set_bittiming callback.

The following 7 patches are by Vincent Mailhol and refactor the
can-dev module and Kbuild, de-inline the can_dropped_invalid_skb()
function, which has grown over the time, and drop outgoing skbs if the
controller is in listen only mode.

Max Staudt's patch fixes a reference in the networking/can.rst
documentation.

Vincent Mailhol provides 2 patches with cleanups for the etas_es58x
driver.

Conor Dooley adds bindings for the mpfs-can to the PolarFire SoC dtsi.

Another patch by me allows the configuration of fixed data bit rates
without need for do_set_data_bittiming callback.

The last 5 patches are by Frank Jungclaus. They prepare the esd_usb
driver to add support for the the CAN-USB/3 device in a later series.

0a2ff7cc8a Bonding: add per-port priority for failover re-selection
Add per port priority support for bonding active slave re-selection during
failover. A higher number means higher priority in selection. The primary
slave still has the highest priority. This option also follows the
primary_reselect rules.

This option could only be configured via netlink.
