IEEE 802.11 wireless stack improvements and bugfixes:
- - Added iwx(4) Tx aggregation support.
- Added an ADDBA_OFFLOAD capability for wifi devices to manage Tx block ack sessions entirely in firmware.
-
- Cached the old BSSID when roaming with iwm(4) so firmware commands can continue using it while roaming to a new AP.
-
- Added support for 40MHz channels to net80211 RA.
+
- Added support for 40MHz channels to net80211 Tx rate adaptation in 11n mode.
- Added monitoring of 20/40MHz channel width changes in beacons sent by our access point, notifying drivers when the channel width has changed.
