http://perforce.freebsd.org/chv.cgi?CH=80453 Change 80453 by sam@sam_ebb on 2005/07/18 16:56:28 Checkpoint backmerge of new scanning+roaming+power save support. While here nuke wiconfig compatbility ioctls and update some api's to conform to vap work. Still more things to cleanup/fix but bg scan+roam works.
