787350ef8d iwlwifi: dbg: remove iwl_fw_cancel_dumps function
Use cancel_delayed_work_sync on the dump workers only in case of
unloading the op mode. In any other case use iwl_fw_flush_dumps or
iwl_fw_dbg_stop_sync (depends if the op mode mutex is held or not).
This way, the driver will wait until debug data is collected in all
cases but op mode unloading.

94b952b55c iwlwifi: mvm: don't log un-decrypted frames
Sometimes the firmware won't be able to decrypt frames
because the keys were not installed yet or other scenarios.
The firmware will soon stop dropping multicast frames when
MAC_FILTER_ACCEPT_GRP is not set. The firmware will simply
always pass multicast frame in.

In order to avoid logging any such frame coming in when we
don't have the keys, drop the print.

5952e0ec3f iwlwifi: mvm: add support for single antenna diversity
There are products which have a single chain with 2 antennas.
In these products, we need to inform the FW that the device has the
single antenna diversity(SAD) feature. In the future, we will read
the active antenna from a BIOS configuration. Currently, we use a
default configuration which means that the FW decides which antenna to use.

fe69b7d124 iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notification
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.

0968fbfa41 iwlwifi: mvm: drop BA sessions on too many old-SN frames
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.

0c18714a0d iwlwifi: pcie: set iwl_trans->cfg later in the probe function
Instead of setting the cfg to iwl_trans already during allocation, set
it only later when we have had the time to decide which cfg to use.
This is part of the effort to be able to decide the cfg based on HW
revision and RF ID after iwl_trans_alloc() has been called.

For now, since we still have a bunch of code checking the HW revision
and the RF ID, we set iwl_trans->cfg early, even before we decided the
real cfg to use.  We only use the trans configuration at this point,
so this is fine for now.  In the future, the trans configuration will
be completely independent from the rest of the config structure, so
we'll be able to avoid this.

Additionally, we can't access the PRPH registers in iwl_trans_alloc()
anymore, so move the HW REV C-step check for family 8000 code later to
the probe function as well.  This step is probably not necessary, but
if that's the case it should be removed separately later on.

79b6c8feb6 iwlwifi: separate elements from cfg that are needed by trans_alloc
In order to be able to select the cfg depending on the HW revision or
on the RF ID, we need to set up the trans before selecting the cfg.
To do so, move the elements from cfg that are needed by
iwl_trans_alloc() to a separate struct at the top of the cfg, so it
can be used by other cfg types as well, before selecting the rest of
the configuration.

6ce1e5c0c2 iwlwifi: support per-platform antenna gain
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.
