http://perforce.freebsd.org/chv.cgi?CH=141938 Change 141938 by sam@sam_ebb on 2008/05/20 23:15:16 Ignore sw beacon miss events when scanning. This is kind of a hack but it is insufficient to manipulate the vap's timer on scan start/end as there may be multiple sta vap's present when a scan is done.
