cfg80211: export expected throughput through get_station()
Users may need information about the expected throughput
towards a given peer.
This value is supposed to consider the size overhead
generated by the 802.11 header.
This value is exported in kbps through the get_station() API
by including it into the station_info object.
Moreover, it is sent to user space when replying to the
nl80211 GET_STATION command.
This information will be useful to the batman-adv module
which will use it for its new metric computation.
