Author: adrian Date: Wed Aug 17 03:04:02 2011 New Revision: 224924 URL: http://svn.freebsd.org/changeset/base/224924 Log: Break out the descriptor and rate control programming and place them in ath_tx_start(). This means the descriptor setup should now be able to be delayed until packet scheduling to the hardware.
