From: Javier Cardona <javier@xxxxxxxxxxx>
We only need to set the skb queue twice:
1. by the netdev, on local TX.
2. when forwarding a mesh frame.
We only need to set the qos header twice:
1. by mac80211, on local TX.
2. when putting a frame on the mpath->frame_queue
We also don't need the RA in order to set the proper queue mapping since
all mesh STAs are QoS, indicate this and do it once when the frame is
received. Also fixes an issue where the QoS header and queue mapping was not
set for unicast forwarded frames.

v4: simplify skb_set_queue and set_qos_hdr calls (Thomas)
I'm sneaking this revision in since John hasn't applied these yet. Sorry for
any inconvenince, but I figured this would be better than submitting a
different patch later which reverts 80% of v3. These
changes take this patch from 14 insertions(+), 4 deletions(-) to:
