Author: adrian Date: Tue Feb 15 13:29:52 2011 New Revision: 218708 URL: http://svn.freebsd.org/changeset/base/218708 Log: Disable flipping antennas for AR9280. Flipping antennas when doing 11n would cause all kinds of strange issues. Just don't do it for now and when it comes time to do it, don't do it here.
