mac80211: Start implementing QoS support for mesh interfaces
In order to support QoS in mesh, we need to assign queue mapping only
after the next hop has been resolved, both for forwarded and locally
originated frames. Also, now that this is fixed, remove the XXX comment
in ieee80211_select_queue().
Also, V-Shy Ho reported that the queue mapping was not being applied to
the forwarded frame (fwd_skb instead of skb). Fixed that as well.

nl80211/cfg80211: add match filtering for sched_scan
Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).
Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan. Only scan results that
match any of the sets will be returned.
At this point, the set consists of a single parameter, an SSID. This
can be easily extended in the future to support more complex matches.

When the rssi of the current AP drops, both wpa_supplicant and the

associate. Since firmware based roaming is faster, inform
wpa_supplicant to avoid roaming and let the firmware decide to
roam if necessary.
For fullmac drivers like ath6kl, it is just enough to provide the
ESSID and the firmware will decide on the BSSID. Since it is not
possible to do pre-auth during roaming for fullmac drivers, the
wpa_supplicant needs to completely disconnect with the old AP and
reconnect with the new AP. This consumes lot of time and it is
better to leave the roaming decision to the firmware.
