Currently, the bandwidth is updated wrongly in BW table in tx_stats
debugfs per sta as there is difference in number of bandwidth type
in mac80211 and driver stats table. This leads to bandwidth getting
updated at wrong index in bandwidth table in tx_stats.
Fix this index mismatch between mac80211 and driver stats table (BW table)
by making the number of bandwidth type in driver compatible with mac80211.

for that particular descriptor. WCN3990 uses ce
descriptors with 64-bit address.
Currently during handling the tx completion of the

using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater

After the FW image was loaded for the first time,

we fail on a consecutive attempt, the driver will abort any dumping.

For non-offloaded rate control, implement VHT extended NSS
support by just ignoring 160 MHz on transmit if the peer
doesn't support the full NSS (2). This is pretty unlikely
and gets us 160 MHz RX as well as TX in most cases, since
the typical case for this workaround is 4x4 AP only doing

When hostapd sends a probe response, it does not request an
acknowledgment on the probe response. This setting is propagated
to the driver and FW from mac80211, and as a result probe responses
are transmitted only once without retries. In congested
environments, this reduces the likelihood for finding the AP.
To overcome this, enable acknowledgment and retries for probe
responses, even in case no acknowledgment is requested. In such
a case the retry limit is set to 3.
