Author: adrian Date: Fri Jul 27 12:08:49 2012 New Revision: 238843 URL: http://svn.freebsd.org/changeset/base/238843 Log: Tidy up the TX status fields a little and add a couple new flags. * shuffle things around so things fall on natural padding boundaries; * add a couple of new flags to specify LDPC and whether to switch to the low power RX chain configuration after this TX has completed.
