Rosen Penev c7c682100c wifi: mt76: mt76_eeprom_override to int 
mt76_eeprom_override has of_get_mac_address, which can return
-EPROBE_DEFER if the nvmem driver gets loaded after mt76 for some
reason.

Make sure this gets passed to probe so that nvmem mac overrides always
work.

Howard Hsu cb6ebbdffe wifi: mt76: mt7996: support writing MAC TXD for AddBA Request 
Support writing MAC TXD for the AddBA Req. Without this commit, the
start sequence number in AddBA Req will be unexpected value for MT7996
and MT7992. This can result in certain stations (e.g., AX200) dropping
packets, leading to ping failures and degraded connectivity. Ensuring
the correct MAC TXD and TXP helps maintain reliable packet transmission
and prevents interoperability issues with affected stations.

Zhi-Jun You 2b660ee10a wifi: mt76: mt7915: fix mt7981 pre-calibration 
In vendor driver, size of group cal and dpd cal for mt7981 includes 6G
although the chip doesn't support it.

mt76 doesn't take this into account which results in reading from the
incorrect offset.

For devices with precal, this would lead to lower bitrate.

Fix this by aligning groupcal size with vendor driver and switch to
freq_list_v2 in mt7915_dpd_freq_idx in order to get the correct offset.

Below are iwinfo of the test device with two clients connected
(iPhone 16, Intel AX210).

Enable 160MHz beamformee support on mt7922 by updating HE capability
element configuration. Previously, only 160MHz channel width was set,
but beamformee for 160MHz was not properly advertised. This patch
adds BEAMFORMEE_MAX_STS_ABOVE_80MHZ_4 capability to allow devices
to utilize 160MHz BW for beamforming.

Tested by connecting to 160MHz-bandwidth beamforming AP and verified
HE capability.

Aaron Lu 0d4eaf8caf sched/fair: Do not balance task to a throttled cfs_rq 
When doing load balance and the target cfs_rq is in throttled hierarchy,
whether to allow balancing there is a question.

The good side to allow balancing is: if the target CPU is idle or less
loaded and the being balanced task is holding some kernel resources,
then it seems a good idea to balance the task there and let the task get
the CPU earlier and release kernel resources sooner. The bad part is, if
the task is not holding any kernel resources, then the balance seems not
that useful.

While theoretically it's debatable, a performance test[0] which involves
200 cgroups and each cgroup runs hackbench(20 sender, 20 receiver) in
pipe mode showed a performance degradation on AMD Genoa when allowing
load balance to throttled cfs_rq. Analysis[1] showed hackbench doesn't
like task migration across LLC boundary. For this reason, add a check in
can_migrate_task() to forbid balancing to a cfs_rq that is in throttled
hierarchy. This reduced task migration a lot and performance restored.

Aaron Lu 253b3f5872 sched/fair: Do not special case tasks in throttled hierarchy 
With the introduction of task based throttle model, task in a throttled
hierarchy is allowed to continue to run till it gets throttled on its
ret2user path.

For this reason, remove those throttled_hierarchy() checks in the
following functions so that those tasks can get their turn as normal
tasks: dequeue_entities(), check_preempt_wakeup_fair() and
yield_to_task_fair().

The benefit of doing it this way is: if those tasks gets the chance to
run earlier and if they hold any kernel resources, they can release
those resources earlier. The downside is, if they don't hold any kernel
resouces, all they can do is to throttle themselves on their way back to
user space so the favor to let them run seems not that useful and for
check_preempt_wakeup_fair(), that favor may be bad for curr.

K Prateek Nayak pointed out prio_changed_fair() can send a throttled
task to check_preempt_wakeup_fair(), further tests showed the affinity
change path from move_queued_task() can also send a throttled task to
check_preempt_wakeup_fair(), that's why the check of task_is_throttled()
in that function.

Aaron Lu fcd394866e sched/fair: update_cfs_group() for throttled cfs_rqs 
With task based throttle model, tasks in a throttled hierarchy are
allowed to continue to run if they are running in kernel mode. For this
reason, PELT clock is not stopped for these cfs_rqs in throttled
hierarchy when they still have tasks running or queued.

Since PELT clock is not stopped, whether to allow update_cfs_group()
doing its job for cfs_rqs which are in throttled hierarchy but still
have tasks running/queued is a question.

The good side is, continue to run update_cfs_group() can get these
cfs_rq entities with an up2date weight and that up2date weight can be
useful to derive an accurate load for the CPU as well as ensure fairness
if multiple tasks of different cgroups are running on the same CPU.
OTOH, as Benjamin Segall pointed: when unthrottle comes around the most
likely correct distribution is the distribution we had at the time of
throttle.

In reality, either way may not matter that much if tasks in throttled
hierarchy don't run in kernel mode for too long. But in case that
happens, let these cfs_rq entities have an up2date weight seems a good
thing to do.
