From: Johannes Berg Date: Thu, 29 Oct 2009 11:19:21 +0000 (+0100) Subject: mac80211: unconditionally set IEEE80211_TX_CTL_SEND_AFTER_DTIM X-Git-Tag: v3.12-rc1~12159^2~449^2~115 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=62b517cb3e974624a2958ad0b603ebb59cd96e16;p=kernel%2Fkernel-generic.git mac80211: unconditionally set IEEE80211_TX_CTL_SEND_AFTER_DTIM When mac80211 is asked to buffer multicast frames in AP mode, it will not set the flag indicating that the frames should be sent after the DTIM beacon for those frames buffered in software. Fix this little inconsistency by always setting that flag in the buffering code path. Signed-off-by: Johannes Berg Signed-off-by: John W.
