      iwlwifi: mvm: use fast balance scan in case of DCM mode with P2P GO · 2ec3ef46
      Ayala Beker authored 
      Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec
the fw fails to allocate events for the P2P GO dtim due to long passive
scan events.

Fix this by requesting all scans in this scenario to be fragmented with
fast balance scan time settings.  The only exception is in case
fragmented scan was planned to be set due to low latency or high
throughput reason, set the scan timing as planned.

      iwlwifi: mvm: introduce a new fragmented scan type: fast balance · 6ff80f18
      Ayala Beker authored 
      Fast balance scan is similar to SCAN_TYPE_MILD, but this scan is
fragmented and has shorter out of operating channel time,
and therefore better match low latency scenarios.

      iwlwifi: trace: change trace to trace one TB at a time · bf77ee2e
      Sara Sharon authored 
      Split TX tracing to be per TB. This is needed now that
AMSDUs can be sent and skb can be larger than trace
limit.

      iwlwifi: pcie: don't pad AMSDU packets · ea74b19d
      Sara Sharon authored 
      When we TX AMSDU, we shouldn't pad the packet. In the past,
we were building AMSDU only in transport layer, and gen2
functions are built based on this. However, now that op mode
may build AMSDUs, we need to take care of padding also in
gen2 "non-pcie-amsdu" path.

      iwlwifi: mvm: don't send keys when entering D3 · 8c7fd6a3
      Sara Sharon authored 
      In the past, we needed to program the keys when entering D3. This was
since we replaced the image. However, now that there is a single
image, this is no longer needed.  Note that RSC is sent separately in
a new command.  This solves issues with newer devices that support PN
offload. Since driver re-sent the keys, the PN got zeroed and the
receiver dropped the next packets, until PN caught up again.

      bnxt_en: Remove unnecessary unsigned integer comparison and initialize variable · 5fc7c12f
      Gustavo A. R. Silva authored 
      There is no need to compare *val.vu32* with < 0 because
such variable is of type u32 (32 bits, unsigned), making it
impossible to hold a negative value. Fix this by removing
such comparison.

Also, initialize variable *max_val* to -1, just in case
it is not initialized to either BNXT_MSIX_VEC_MAX or
BNXT_MSIX_VEC_MIN_MAX before using it in a comparison
with val.vu32 at line 159:

	if (val.vu32 > max_val)

* fixes for 'iw' output: rates for enabled SGI, 'dump station'

* expose more scan features to host: scan flush and dwell time

* inform cfg80211 when OBSS is not supported by firmware

wlcore

* add support for optional wakeirq

ath10k

* retrieve MAC address from system firmware if provided

* support extended board data download for dual-band QCA9984

* extended per sta tx statistics support via debugfs

* average ack rssi support for data frames

* speed up QCA6174 and QCA9377 firmware download using diag Copy
