Author: rpaulo Date: Tue Sep 22 18:18:14 2009 New Revision: 197413 URL: http://svn.freebsd.org/changeset/base/197413 Log: Update 802.11s mesh support to draft 3.03. This includes a revised frame format for peering and changes to the PERR frames. Note that this is incompatible with the previous code.
