New Revision: 235804
URL: http://svn.freebsd.org/changeset/base/235804

Log:
  Re-up the TX ath_buf limit from 128 to 512.
  
  I'll have to leave this high for now, until I've done some significant
  surgery with how ath_bufs (and descriptors) are handled.
  
  This should significantly cut down on the opportunities for a full TX
  queue hanging traffic.  I'll continue making things work though; I'm
  mostly doing this for users. :)
