Merge tag 'wireless-drivers-next-for-davem-2018-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says: ==================== wireless-drivers-next patches for 4.17 The biggest changes are the bluetooth related patches to the rsi driver. It adds a new bluetooth driver which communicates directly with the wireless driver and the interface is defined in include/net/rsi_91x.h. Major changes: wl1251 * read the MAC address from the NVS file rtlwifi * enable mac80211 fast-tx support mt76 * add capability to select tx/rx antennas mt7601 * let mac80211 validate rx CCMP Packet Number (PN) rsi * bluetooth: add new btrsi driver * btcoex support with the new btrsi driver ==================== Signed-off-by: David S.
