wireless-drivers-next patches for 4.16 

The most important here is the ssb fix, it has been reported by the
 users frequently and the fix just missed the final v4.15. Also
 numerous other fixes, mt76 had multiple problems with aggregation and
 a long standing unaligned access bug in rtlwifi is finally fixed.
 
 Major changes:
 
 ath10k
 
 * correct firmware RAM dump length for QCA6174/QCA9377
 
 * add new QCA988X device id
 
 * fix a kernel panic during pci probe
 
 * revert a recent commit which broke ath10k firmware metadata parsing
 
 ath9k
 
 * fix a noise floor regression introduced during the merge window
 
 * add new device id
 
 rtlwifi
 
 * fix unaligned access seen on ARM architecture
 
 mt76
 
 * various aggregation fixes which fix connection stalls
 
 ssb
 
 * fix b43 and b44 on non-MIPS which broke in v4.15-rc9
