QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz.
First, report this to user-space by setting the max-tx-speed
and max-rx-speed vht capabilities.
Second, if the peer rx-speed is configured, and if we
are in 160 or 80+80 mode, and the peer rx-speed matches
the max speed for 2x2 or 1x1 at 160Mhz (long guard interval),
then use that info to set the peer_bw_rxnss_override appropriately.
Without this, a 9984 firmware will not use 2x2 ratesets when
transmitting to peer (it will be stuck at 1x1), because
the firmware would not have configured the rxnss_override.

The ath10k firmware doesn't announce its VHT channel width capabilities in
the vht_cap information from the "service ready event" arguments. The
driver must therefore check whether the 160MHz short GI bit is set and
whether the driver still doesn't set the bits for the 160/80+80 MHz
capabilities.
The two bits for the channel width are a two bit integer and not two
separate bits which cannot be parsed without the knowledge of the other
bit. Using IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ (b10..) as a
mask for this task doesn't make any sense. The correct mask for the VHT
channel width should be used instead to make this check more readable.

to the two-second timeout.

This reverts commit b057886524 ("ath10k: do not use coherent memory for
allocated device memory chunks") in 2015 which converted this allocation from
dma_map_coherent() to kzalloc() / dma_map_single().
The current problem manifests when using later model NICs with larger
(>700KiB) scratch spaces in memory. Although the kzalloc call
succeeds, the software IOMMU TLB code (via dma_map_single()) panics
because it can't find 700KiB of linear physmem bounce buffers for DMA.
Now, this is a bit of a silly failure mode for the dma map API,
but it's what we currently have to play with.
In these cases, doing kzalloc() works fine, but the dma_map_single()
call fails.
After chatting with Linus briefly about this, it indeed should be
using dma_alloc_coherent() for doing larger device memory allocation
that requires some kind of physical address mapping.
You're not supposed to be using kzalloc and dma_map_* calls for
large memory regions, and I'm guessing not for long-held mappings
either. Typically dma mappings should be temporary for DMA,
not long held like these.
Now, since hopefully the major annoying underlying problem has also been
addressed (ie, ath10k is no longer tears down all of these allocations
and reallocates them every time the vdevs are brought down) fragmentation
should stop being such a touchy issue. If it is though, using
dma_alloc_coherent() use gets us access to the CMB APIs too relatively
easily and ideally we would be allocating memory early in boot for
exactly these reasons.

The QCA4019 firmware 10.4-3.2.1-00050 reports only HT MCS rates between
0-9. But 802.11n MCS rates can be larger than that. For example a 2x2
device can send with up to MCS 15.
The firmware encodes the higher MCS rates using the NSS field. The actual
calculation is not documented by QCA but it seems like the NSS field can be
mapped for HT rates to following MCS offsets:
* NSS 1: 0
* NSS 2: 8
* NSS 3: 16
* NSS 4: 24
This offset therefore has to be added for HT rates before they are stored
in the rate_info struct.

Code refactorization:
Moved the code for ep 0 in ath10k_htc_rx_completion_handler
to ath10k_htc_control_rx_complete.
This eases the implementation of SDIO/mbox significantly since
the ep_rx_complete cb is invoked directly from the SDIO/mbox
hif layer.
Since the ath10k_htc_control_rx_complete already is present
(only containing a warning message) there is no reason for not
using it (instead of having a special case for ep 0 in
ath10k_htc_rx_completion_handler).

This patch moves the HTC ctrl service connect from
htc_wait_target to htc_init.
This is done in order to make sure the htc ctrl service
is setup properly before hif_start is called.
The reason for this is that we want the HTC ctrl service
callback to be initialized before the target sends the
HTC ready message.
The ready message will always be transmitted on endpoint 0
(which is always assigned to the HTC control service) so it
makes more sense if HTC control has been connected before the
ready message is received.
Since the service to pipe mapping is done as a part of
the service connect, the get_default_pipe call is redundant
and was removed.

spectral_bin length (number of bins per fft sample) is usually
a value where (2^n = value), n is an integer. All of the QCA99X0
family of chipsets seems to report a spectral_bin length of
2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm'
bytes seems to carry some radar related info which is currently
discarded only for 'bin_len = 68' bytes. Extend this discarding of
irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by
introducing a hardware parameter 'spectral_bin_discard'. Also
for QCA988X based family of chipsets which doesn't seem to have this
issue and also for some of the hardware which I have not tested
like QCA6174/QCA9377 the existing behaviour is retained as it is.

In 'ath10k_ce_alloc_pipe' the compile time sanity check to
ensure that there is sufficient buffers in CE4 for HTT Tx
MSDU descriptors, but this did not take into account of the
case with 'peer flow control' enabled, fix this.

Add an ath10k HTC debug message when insufficient tx credits
are available to send the WMI commands. This is very useful
in debugging issues like 'tx credit starvation' that could
possibly happen with multiclient setup with constant roaming

It seems set_coverage_class_work is not cancelled anywhere,
though I could not find a crash/warning with this existing
design, its safer to cancel it during stop() and also before
restarting the hardware.

If station advertises diffferent NSS capabilities in Rx_mcs set
of HT and VHT IEs in assoc req, the current NSS computation
logic configures the NSS support only based on Rx_mcs set of
HT capabilities in the driver. This is configuring the station
NSS capabilities incorreclty in the target.
For example, if station advertise Rx_mcs set as 2 spatial streams
in HT capabilities and 1 spatial streams in VHT capabilities in
assoc request, as per current logic we are calculating nss from
HT capabilities and the driver sets peer_num_spatial_streams as
2 for the station which is configured in VHT 1*1.
This patchs fix this issue by calculating the nss from VHT cap if
station supports vht.

Move NAPI enable to 'ath10k_ahb_hif_start' from
'ath10k_ahb_hif_power_up'. This is to maintain the symmetry
of calling napi_enable() from ath10k_ahb_hif_start() so that it
matches with napi_disable() being called from ath10k_pci_hif_stop().
This change is based on the crash fix from Kalle for PCI interface in
commit 1427228d58 ("ath10k: fix napi crash during rmmod when probe
firmware fails").
