[B.A.T.M.A.N.] [PATCH 3/7] mac80211: add new RC API to retrieve expected throughput

[Antonio Quartulli <antonio@meshcoding.com>]

From: Antonio Quartulli <antonio@open-mesh.com>

In order to make mac80211 export the expected throughput,
a new API which extracts such information from any mac80211
SW RC algorithm is needed.
Therefore add the new get_expected_throughput() member
to the rate_control_ops structure.

The exported value is expressed in Mbps/100. Such unit has
been chosen because it is the highest precision that
MinstrelHT can return.
