We will soon be using a new notification that will be
initiated by the driver, sent to the firmware and sent
back to all the RSS queues by the firmware. This new
notification will be useful to synchronize the NSSN across
all the queues.
For now, don't send the notification, just add the code to
handle it. Later patch will add the code to actually send
it.
While at it, validate the baid coming from the firmware to
avoid accessing an array with a bad index in the driver.

Firmware versions before 41 don't support the GEO_TX_POWER_LIMIT
command, and sending it to the firmware will cause a firmware crash.
We allow this via debugfs, so we need to return an error value in case
it's not supported.
This had already been fixed during init, when we send the command if
the ACPI WGDS table is present. Fix it also for the other,
userspace-triggered case.

On older NICs, we occasionally see issues with A-MSDU support,
where the commands in the FIFO get confused and then we see an
assert EDC because the next command in the FIFO isn't TX.
We've tried to isolate this issue and understand where it comes
from, but haven't found any errors in building the A-MSDU in
software.
At least for now, disable A-MSDU support on older hardware so
that users can use it again without fearing the assert.

with the per-controller ns is run through revalidate_disk when a

This prevents online resizing of nvme block devices and in extension of

Windows guest can't run after force-TDR with host log:

...
The error is raised by set_context_ppgtt_from_shadow(), when it checks

In work thread before each submission, a shadow_mm is set to shadowed in:
shadow_ppgtt_mm()
<-intel_vgpu_pin_mm()
<-prepare_workload()
<-dispatch_workload()
<-workload_thread()
However checking whether or not shadow_mm is shadowed is prior to it:
set_context_ppgtt_from_shadow()
<-dispatch_workload()
<-workload_thread()
In normal case, create workload will check the existence of shadow_mm,
if not it will create a new one and marked as shadowed. If already exist
it will reuse the old one. Since shadow_mm is reused, checking of shadowed
in set_context_ppgtt_from_shadow() actually always see the state set in
creation, but not the state set in intel_vgpu_pin_mm().
When force-TDR, all engines are reset, since it's not dmlr level, all
ppgtt_mm are invalidated but not destroyed. Invalidation will mark all
reused shadow_mm as not shadowed but still keeps in ppgtt_mm_list_head.
If workload submission phase those shadow_mm are reused with shadowed
not set, then set_context_ppgtt_from_shadow() will report error.
