That would be fine with me. As I said though, there are more patches than this one needed for full features and interoperability. The person that sent me the mac80211/wireless patches, and hostapd for that matter, may be able to put something together for upstream, but I am not sure if they will have time. I don't currently feel motivated enough to try to clean it all up and try to push it upstream myself. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
