New Revision: 302030
URL: https://svnweb.freebsd.org/changeset/base/302030

Log:
  [ath] implement TX queue configuration extensions for the AR9380 HAL.
  
  Among other things, this introduces the idea of DBA-gated queues that
  aren't the CABQ.  The TDMA support requires this.
  
  Tested:
  
  * AR9580 (hostap mode)
  * AR9380 (sta mode)
  
  Approved by:	re (gjb)
