svn commit: r225393 - user/adrian/if_ath_tx/sys/dev/ath

New Revision: 225393
URL: http://svn.freebsd.org/changeset/base/225393

Log:
  Hacky work around for now - disable the last rate series entry
  when forming aggregates. This is a very low MCS rate in all MCS
  instances and the 4ms frame length limit ends up being quite low.
  Thus larger aggregates don't get a chance to form.
  
  This isn't optimal..
