mac80211: Fix regression in mesh forwarding path.
The removal of the master netdev broke the mesh forwarding path. This patch fixes it by using the new internal 'pending' queue. As a result of this change, mesh forwarding no longer does the inefficient 802.11 -> 802.3 -> 802.11 conversion that was done before. [Changes since v1] Suggested by Johannes: - Select queue before adding to mpath queue - ieee80211_add_pending_skb -> ieee80211_add_pending_skbs - Remove unnecessary header wme.h Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Reviewed-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
