From: Johannes Berg Date: Mon, 18 Jul 2011 16:08:36 +0000 (+0200) Subject: mac80211: implement scan supported rates X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=85a237fe308405ee38eb9c6733571c49902ec229;p=linux-beck.git mac80211: implement scan supported rates Scanning currently uses the TX rate mask to restrict the rate set, which is bogus. Make it use the new set of rates from userspace. Signed-off-by: Johannes Berg Signed-off-by: John W.
