From: Antonio Quartulli <antonio@xxxxxxxxxxxxx>
Implement and export the new cfg80211_get_station() API.
This utility can be used by other kernel modules to obtain
detailed information about a given wireless station.
It will be in particular useful to batman-adv which will
implement a wireless rate based metric.
