A couple more fixes: 

* don't try to authenticate during reconfiguration, which causes
    drivers to get confused
  * fix a kernel-doc warning for a recently merged change
  * fix MU-MIMO group configuration (relevant only for monitor mode)
  * more rate flags fix: remove stray RX_ENC_FLAG_40MHZ
  * fix IBSS probe response allocation size
