New Revision: 235134
URL: http://svn.freebsd.org/changeset/base/235134

Log:
  Re-enable this particular DELAY() for now, at least until the
  TX and RX PCU stop/drain routines have been thoroughly debugged.
  
  It's also very likely that I should add hooks back up to the
  interface glue (if_ath_pci / if_ath_ahb) to do any relevant
  bus flushes that are required.  A WMAC DDR flush may be required
  for the AR9130 SoC.
