Author: adrian Date: Mon May 7 18:30:22 2012 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.
