Author: adrian Date: Sat Nov 3 22:13:42 2012 New Revision: 242528 URL: http://svn.freebsd.org/changeset/base/242528 Log: For AR9380 NICs - the non-enterprise versions don't support RTS protection of small (< 256 byte) aggregate frames. This needs to be done or 11n aggregation TX just simply doesn't work on these NICs. Whilst here, extend some debug printing; I was using this whilst debugging the TX power setup in the TX descriptor(s) on the AR9380.
