New Revision: 248717
URL: http://svnweb.freebsd.org/changeset/base/248717

Log:
  Remove the mcast path calls to ath_hal_gettxdesclinkptr() for axq_link -
  they're no longer needed for the legacy path and they're not wanted
  for the EDMA path.
  
  Tested:
  
  * AR9280, hostap + CABQ
  * AR9380/AR9580, hostap + CABQ
