processing the events ahead of ACL packets.
It worth noting though that priorizing events over ACL data may result
in inverting the order compared to how they appeared over the air, for

Commit
4dfb9982644b ("tsn: Fix build.") fixed compilation with const
dev_addr. In tsnep_netdev_set_mac_address() the call of ether_addr_copy()
was replaced with dev_set_mac_address(), which calls
ndo_set_mac_address(). This results in an endless recursive loop because
ndo_set_mac_address is set to tsnep_netdev_set_mac_address.
Call eth_hw_addr_set() instead of dev_set_mac_address() in
ndo_set_mac_address()/tsnep_netdev_set_mac_address() to copy the address
as intended.

In mirror mode a port is set as mirror and other port are configured

the mirror port is disabled and reverted to normal port.
The switch supports max 4 LAG with 4 different member max.
Current supported mode is Hash mode in both L2 or L2+3 mode.
There is a problematic implementation for the hash mode where

change the hash mode as it's global.
When a member of the LAG is disconnected, the traffic is redirected

mctp: Add MCTP-over-serial transport binding
This change adds a MCTP Serial transport binding, as defined by DMTF
specificiation DSP0253 - "MCTP Serial Transport Binding". This is
implemented as a new serial line discipline, and can be attached to
arbitrary tty devices.
From the Kconfig description:
This driver provides an MCTP-over-serial interface, through a
serial line-discipline, as defined by DMTF specification "DSP0253 -
MCTP Serial Transport Binding". By attaching the ldisc to a serial
device, we get a new net device to transport MCTP packets.
This allows communication with external MCTP endpoints which use
serial as their transport. It can also be used as an easy way to
provide MCTP connectivity between virtual machines, by forwarding
data between simple virtual serial devices.
Say y here if you need to connect to MCTP endpoints over serial. To
compile as a module, use m; the module will be called mctp-serial.
Once the N_MCTP line discipline is set [using ioctl(TCIOSETD)], we get a
new netdev suitable for MCTP communication.
The 'mctp' utility[1] provides a simple wrapper for this ioctl, using
'link serial <device>':
# mctp link serial /dev/ttyS0 &
# mctp link
dev lo index 1 address 0x00:00:00:00:00:00 net 1 mtu 65536 up
dev mctpserial0 index 5 address 0x(no-addr) net 1 mtu 68 down

mlxsw: Various updates
Patch #1 removes deadcode reported by Coverity.
Patch #2 adds a shutdown method in the PCI driver to ensure the kexeced

mlxsw: pci: Add shutdown method in PCI driver
On an arm64 platform with the Spectrum ASIC, after loading and executing
a new kernel via kexec, the following trace [1] is observed. This seems
to be caused by the fact that the device is not properly shutdown before
executing the new kernel.
Fix this by implementing a shutdown method which mirrors the remove
method, as recommended by the kexec maintainer [2][3].

Merge branch 'qca8k-next'
Ansuel Smith says:
====================
Multiple cleanup and feature for qca8k
This is a reduced version of the old massive series.
Refer to the changelog to know what is removed from this.
We clean and convert the driver to GENMASK FIELD_PREP to clean multiple
use of various naming scheme. (example we have a mix of _MASK, _S _M,
and various name) The idea is to ""simplify"" and remove some shift and
data handling by using FIELD API.
The patch contains various checkpatch warning and are ignored to not
create more mess in the header file. (fixing the too long line warning
would results in regs definition less readable)
We conver the driver to regmap API as ipq40xx SoC is based on the same
reg structure and we need to generilize the read/write access to split
the driver to commond and specific code.
The conversion to regmap is NOT done for the read/write/rmw operation,
the function are reworked to use the regmap helper instead.
This is done to keep the patch delta low but will come sooner or later
when the code will be split.
Any new feature will directly use the regmap helper and the reg
set/clear and the busy wait function are migrated to regmap helper as
the use of these function is low.
We also add a minor patch for MIB counter as qca8337 is missing 2 extra
counter, support for mdb and ageing settings.
v3:
- Try to reduce regmap conversion patch
v2:
- Move regmap init to sw_probe instead of moving switch id check.
- Removed LAGs, mirror extra features will come later in another
smaller series.
- Squash 2 ageing patch
- Add more description about the regmap patch
- Rework mdb patch to do operation under the same lock

Ipq40xx SoC have the internal switch based on the qca8k regmap but use
