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.

Instead of allocating memory for which we have an upper

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.

The layout of the RBD (receive buffer descriptor) isn't quite right,
the hardware ended up being implemented differently. Switch to the
correct RBD layout. While at it, remove the now useless extra defines.
Also, switch the CD (completion descriptor) to the right format, which
is basically just a code cleanup because the only field we really used
(rbid) is still in the same place. We may need fragmentation later if
we ever want to use it.

Implement CSI (channel estimation matrix) reporting in the mvm
driver, if the firmware has the capability.
Currently only a debugfs API is provided as the API is still
under discussion.
For now, RX aggregation must be disabled to use this feature
on data frames as we haven't found a good way to attach the
data to A-MPDUs, given complexities with multi-queue.

Take the NSS value from 'rx_vec' rather than from 'rate_n_flags'.
The rate_n_flags has only 2 bits for the NSS giving a max of 4SS
(0 = 1SS etc.). Since there may be up to 8SS use the rx_vec which
has 3 bits for the NSS.
While at it, fix the rx_vec array to length of 2.

The firmware changed the PHY data API, so follow suit.
Some data is now available even for HT/VHT frames, so
the info type in the metadata was changed. This change
isn't backwards compatible, but
1) the firmware with the old API was never released;
2) the only overlap in the info type field is from the
old type of TB to the new of HT, so this basically
just means that with older FW and newer driver the
data will be considered missing.
While at it, remove the extra code to set the LTF syms
corresponding to the streams and use the data from the
device instead - we don't really need this in any case
other than when we have it from the device.
As the new API gives use the spatial reuse 1-4 fields
for trigger-based PPDUs, also expose that to radiotap.

When the info type is MU, we still have the data from the TSF
overload words, so should decode that. When it's MU_EXT_INFO
we additionally have the SIG-B common 0/1/2 fields.
Also document the validity depending on the info type and fix
the name of the regular TB PPDU info type accordingly.

Implement the extended HE-MU info type decoding to show the HE-SIG-B
common contents in the HE-MU radiotap field.
The DW4 data is partially overwritten by the hardware in all cases, so
only the higher 16 bits can be used. To be able to use it for the HE
SIG-B common data anyway, move the bits around in the following way:
SIG-B common 0: DW 4 -> DW 7
SIG-B common 1: DW 7 -> DW 8
SIG-B common 2: DW 8 -> DW 4 (upper half)

Currently multi-queue is disabled for 22000 devices.
This was since driver isn't supposed to write to prph
registers anymore, and FW needs to configure the RFH.
Now that FW added support for the API - use it and remove
the 22000 multi RX queue disablement.
Bump min API version to avoid compatibility issues.

In some cases we may get from FW errored frames with
UNKNOWN security type.
This may happen in unsecured aggregation flow, where
the first packet had a CRC error in the WEP bit, which
was followed by a failure to decrypt and was dropped.
The next frames in the aggregation "inherit" the bad metadata
of the first packet.
Make sure to drop such frames since RADA and other offloads
will not operate correctly which may have unexpected results.
In case of AP it also causes to TX AMSDU frames to the peers,
resulting with assert 0x104B.

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.
While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.
