X-Git-Tag: v2.6.39-rc1~468^2~403^2~43 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2cf22b897c63df65e7360a1897e5312c58617fbd;p=platform%2Fkernel%2Flinux-stable.git mac80211: Recalculate channel-type on iface removal. When a vif goes away, it could cause the super-chan to be recalculated differently, so do that calculation on iface removal. Signed-off-by: Ben Greear Acked-by: Johannes Berg Signed-off-by: John W.
