The "Expected throughput" towards a generic wireless peer is a value that can be used by other kernel components to achieve different goals. In particular we have 802.11s and batman-adv which will iuse this estimation to compute their throughput based metric. Therefore with this patchset I wanted to export this result and make it available for future use.
Changes included in this patchset: - add the new get_expected_throughput() RC API - export the result of such API via cfg80211::get_station() - implement the get_expected_throughput() RC API for minstrel(_ht)
For what concerns Minstrel_HT I decided to directly re-use the throughput value computed by the algorithm itself with minstrel_ht_calc_tp() for max_tp_rate.
For the legacy Minstrel instead I computed the expected throughput as the product of the max_tp bitrate multplied by its probability of success.
I am not entirely sure about passing sband as third parameter to get_expected_throughput()..maybe somebody can suggest a better solution.
