net: ethernet: dwmac: oxnas glue removal
With [1] removing MPCore SMP support, this makes the OX820 barely usable,
associated with a clear lack of maintainance, development and migration to
dt-schema it's clear that Linux support for OX810 and OX820 should be removed.
In addition, the OX810 hasn't been booted for years and isn't even present
in an ARM config file.
For the OX820, lack of USB and SATA support makes the platform not usable
in the current Linux support and relies on off-tree drivers hacked from the
vendor (defunct for years) sources.
The last users are in the OpenWRT distribution, and today's removal means
support will still be in stable 6.1 LTS kernel until end of 2026.
If someone wants to take over the development even with lack of SMP, I'll
be happy to hand off maintainance.
It has been a fun time adding support for this architecture, but it's time
to get over!

====================
selftests: New selftests for out-of-order-operations patches in mlxsw
In the past, the mlxsw driver made the assumption that the user applies
configuration in a bottom-up manner. Thus netdevices needed to be added to
the bridge before IP addresses were configured on that bridge or SVI added
on top of it, because whatever happened before a netdevice was mlxsw upper
was generally ignored by mlxsw. Recently, several patch series were pushed
to introduce the bookkeeping and replays necessary to offload the full
state, not just the immediate configuration step.
In this patchset, introduce new selftests that directly exercise the out of
order code paths in mlxsw.
- Patch #1 adds new tests into the existing selftest router_bridge.sh.
- Patches #2-#5 add new generic selftests.
- Patches #6-#8 add new mlxsw-specific selftests.

Add two tests to deslave a port from and reenslave to a bridge. This should
retain the ability of the system to forward traffic, but on an offloading
driver that is sensitive to ordering of operations, it might not.
The first test does this configuration in a way that relies on
vlan_default_pvid to assign the PVID. The second test disables that
autoconfiguration and configures PVID by hand in a separate step.

Add TJA1120 support
This patch series got bigger than I expected. It cleans up the
next-c45-tja11xx driver and adds support for the TJA1120(1000BaseT1
automotive phy).
Master/slave custom implementation was replaced with the generic
implementation (genphy_c45_config_aneg/genphy_c45_read_status).
The TJA1120 and TJA1103 are a bit different when it comes to the PTP
interface. The timestamp read procedure was changed, some addresses were
changed and some bits were moved from one register to another. Adding
TJA1120 support was tricky, and I tried not to duplicate the code. If
something looks too hacky to you, I am open to suggestions.

During PTP testing on early TJA1120 engineering samples I observed that
if the link is lost and recovered, the tx timestamps will be randomly
lost. To avoid this HW issue, the PCS should be reset.
Resetting the PCS will break the link and we should reset the PCS on
LINK UP -> LINK DOWN transition, otherwise we will trigger and infinite
loop of LINK UP -> LINK DOWN events.

On TJA1120, the external trigger timestamp now has a VALID bit. This
changes the logic and we can't use the TJA1103 procedure.
For TJA1103, we can always read a valid timestamp from the registers,
compare the new timestamp with the old timestamp and, if they are not the
same, an event occurred. This logic cannot be applied for TJA1120 because
the timestamp is 0 if the VALID bit is not set.

The egress timestamp FIFO/circular buffer work different on TJA1120 than
TJA1103.
For TJA1103 the new timestamp should be manually moved from the FIFO to
the hardware buffer before checking if the timestamp is valid.
For TJA1120 the hardware will move automatically the new timestamp
from the FIFO to the buffer and the user should check the valid bit, read
the timestamp and unlock the buffer by writing any of the buffer
registers(which are read only).
Another change for the TJA1120 is the behaviour of the EGR TS IRQ bit.
This bit was a self-clear bit for TJA1103, but now should be cleared
before reading the timestamp.

virtio_net: add per queue interrupt coalescing support
Currently, coalescing parameters are grouped for all transmit and receive
virtqueues. This patch series add support to set or get the parameters for
a specified virtqueue.
When the traffic between virtqueues is unbalanced, for example, one virtqueue
is busy and another virtqueue is idle, then it will be very useful to
control coalescing parameters at the virtqueue granularity.
Example command:
$ ethtool -Q eth5 queue_mask 0x1 --coalesce tx-packets 10
Would set max_packets=10 to VQ 1.
$ ethtool -Q eth5 queue_mask 0x1 --coalesce rx-packets 10

Address learning should initially be turned off by the driver for port
operation in standalone mode, then the DSA core handles changes to it
via ds->ops->port_bridge_flags().
Currently this is not the case for qca8k where learning is enabled
unconditionally in qca8k_setup for every user port.
Handle ports configured in standalone mode by making the learning
configurable and not enabling it by default.
Implement .port_pre_bridge_flags and .port_bridge_flags dsa ops to
enable learning for bridge that request it and tweak
.port_stp_state_set to correctly disable learning when port is
configured in standalone mode.

net/sched: improve class lifetime handling
Valis says[0]:
============
Three classifiers (cls_fw, cls_u32 and cls_route) always copy
tcf_result struct into the new instance of the filter on update.
This causes a problem when updating a filter bound to a class,
as tcf_unbind_filter() is always called on the old instance in the
success path, decreasing filter_cnt of the still referenced class
and allowing it to be deleted, leading to a use-after-free.
============
Turns out these could have been spotted easily with proper warnings.
Improve the current class lifetime with wrappers that check for
overflow/underflow.
While at it add an extack for when a class in use is deleted.

The 'filter_cnt' counter is used to control a Qdisc class lifetime.
Each filter referecing this class by its id will eventually
increment/decrement this counter in their respective
'add/update/delete' routines.
As these operations are always serialized under rtnl lock, we don't
need an atomic type like 'refcount_t'.
It also means that we lose the overflow/underflow checks already
present in refcount_t, which are valuable to hunt down bugs
where the unsigned counter wraps around as it aids automated tools
like syzkaller to scream in such situations.
Wrap the open coded increment/decrement into helper functions and
add overflow checks to the operations.

Matthieu Baerts says:
====================
mptcp: cleanup and improvements in the selftests
This small series of 4 patches adds some improvements in MPTCP
selftests:
- Patch 1 reworks the detailed report of mptcp_join.sh selftest to
better display what went well or wrong per test.
- Patch 2 adds colours (if supported, forced and/or not disabled) in
mptcp_join.sh selftest output to help spotting issues.
- Patch 3 modifies an MPTCP selftest tool to interact with the
path-manager via Netlink to always look for errors if any. This makes
sure odd behaviours can be seen in the logs and errors can be caught
later if needed.
- Patch 4 removes stdout and stderr redirections to /dev/null when using
pm_nl_ctl if no errors are expected in order to log odd behaviours.

All pm_nl_ctl commands were muted. If there was an unexpected error with
one of them, this was simply not visible in the logs, making the
analysis very hard. It could also hide misuse of commands by mistake.
Now the output is only muted when we do expect to have an error, e.g.
when giving invalid arguments on purpose.

If a Netlink command for the MPTCP path-managers is not valid, it is
important to check if there are errors. If yes, they need to be reported
instead of being ignored and exiting without errors.
Now if no replies are expected, an ACK from the kernelspace is asked by
the userspace in order to always expect a reply. We can use the same
buffer that is currently always >1024 bytes. Then we can check if there
is an error (err->error), print it if any and report the error.
After this modification, it is required to mute expected errors in
mptcp_join.sh and pm_netlink.sh selftests:
- when trying to add a bad endpoint, e.g. duplicated
- when trying to set the two limits above the hard limit

Thanks to the parent commit, it is easy to change the output and add
some colours to help spotting issues.
The colours are not used if stdout is redirected or if NO_COLOR env var
is set to 1 as specified in https://no-color.org.
It is possible to force displaying the colours even if stdout is
redirected by setting this env var:
SELFTESTS_MPTCP_LIB_COLOR_FORCE=1

This patch modifies how the detailed results are printed, mainly to
improve what is displayed in case of issue:
- Now the test name (title) is printed earlier, when starting the test
if it is not intentionally skipped: by doing that, errors linked to
a test will be printed after having written the test name and then
avoid confusions.
- Due to the previous item, it is required to add a new line after
having printed the test name because in case of error with a command,
it is better not to have the output in the middle of the screen.
- Each check is printed on a dedicated line with aligned status (ok,
skip, fail): it is easier to spot which one has failed, simpler to
manage in the code not having to deal with alignment case by case and
helpers can be used to uniform what is done. These helpers can also be
useful later to do more actions depending on the results or change in
one place what is printed.
- Info messages have been reduced and aligned as well. And info messages
about the creation of the default test files of 1 KB are no longer
printed.
Example:
001 no JOIN
syn [ ok ]
synack [ ok ]
ack [ ok ]
Or with a skip and a failure:
001 no JOIN
syn [ ok ]
synack [fail] got 42 JOIN[s] synack expected 0
Server ns stats
(...)
Client ns stats
(...)
ack [skip]
Or with info:
104 Infinite map
Test file (size 128 KB) for client
Test file (size 128 KB) for server
file received by server has inverted byte at 169
5 corrupted pkts
syn [ ok ]
synack [ ok ]
While at it, verify_listener_events() now also print more info in case
of failure and in pm_nl_check_endpoint(), the test is marked as failed
instead of skipped if no ID has been given (internal selftest issue).
