Merge tag 'wireless-drivers-next-2020-01-26' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says: ==================== wireless-drivers-next patches for v5.6 Second set of patches for v5.6. Nothing special standing out, smaller new features and fixes allover. Major changes: ar5523 * add support for SMCWUSBT-G2 USB device iwlwifi * support new versions of the FTM FW APIs * support new version of the beacon template FW API * print some extra information when the driver is loaded rtw88 * support wowlan feature for 8822c * add support for WIPHY_WOWLAN_NET_DETECT brcmfmac * add initial support for monitor mode qtnfmac * add module parameter to enable DFS offloading in firmware * add support for STA HE rates * add support for TWT responder and spatial reuse ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
