Rodriguez" Date: Sat, 21 Feb 2009 00:20:38 -0500 Subject: [PATCH] cfg80211: enable 5 GHz world roaming channels The current static world regulatory domain is too restrictive, we can use some 5 GHz channels world wide so long as they do not touch frequencies which require DFS. The compromise is we must also enforce passive scanning and disallow usage of a mode of operation that beacons: (AP | IBSS | Mesh) Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
