http://perforce.freebsd.org/chv.cgi?CH=38544 Change 38544 by sam@sam_ebb on 2003/09/24 14:53:56 Correct rate set negotiation when operating as a station: if the AP has basic rates that we do not support then ignore them instead of marking the rate set in error. This fixes an 11b station associating with an 11g/b AP.
