36 as well, but not all 8000 family got this feature enabled.  The

entirely.  If we try to send this command to the firmwares that do not
support it, we get a BAD_COMMAND response from the firmware.

Without CONFIG_THERMAL, the driver fails to link as it calls

In prior hardware generations (e.g. 9000 series), we received the BAR
frame with fake NSSN information to handle releasing frames from the
reorder buffer for the default queue, the other queues were getting
the FRAME_RELEASE notification in this case.

With multi-TID block-ack, the firmware no longer sends us the BAR
frame because the fake RX is quite big (just the metadata is around
48 bytes or so). Instead, it now sends us one (or multiple) special
release notifications (0xc2). The hardware consumes these as well,
but only generates the FRAME_RELEASE (0xc3) for queues other than
the default queue. We thus need to handle them in the same way we
handle the normal FRAME_RELEASE.

Certain APs (I think a certain Broadcom model) interact badly with our
full state BA bitmap handling, and if triggered badly with many powersave
transitions they keep sending frames from before the window, which our
hardware then doesn't appear to ACK (to them) since it has moved on and
is sending ACKs for higher SNs now.

Try to detect this situation and if this keeps happening, disable the
aggregation session.

can be used by other cfg types as well, before selecting the rest of

TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.
