From: Antonio Quartulli <antonio@xxxxxxxxxxxxx>
Users may need information about the expected throughput
towards a given peer computed by the RC algorithm.
Export such value through the get_station() API.
This information is useful to the batman-adv module which
will use it for its new metric computation.
