Johannes Berg says:
====================
Back from a long absence, so we have a number of things:
* a remain-on-channel fix from Avi
* hwsim TX power fix from Beni
* null-PTR dereference with iTXQ in some rare configurations (Chunho)
* 40 MHz custom regdomain fixes (Emmanuel)
* look at right place in HT/VHT capability parsing (Igor)
* complete A-MPDU teardown properly (Ilan)
* Mesh ID Element ordering fix (Liad)
* avoid tracing warning in ht_dbg() (Sharon)
* fix print of assoc/reassoc (Simon)
* fix encrypted VLAN with iTXQ (myself)
* fix calling context of TX queue wake (myself)
* fix a deadlock with ath10k aggregation (myself)
