From: Eliad Peller <eliad@xxxxxxxxxx>
Drivers might want to have private data in addition
to all other ieee80211_tx_info.status fields.
The current ieee80211_tx_info.rate_driver_data overlaps
with some of the non-rate data (e.g. ampdu_ack_len), so
it might not be good enough.
Since we already know how much free bytes remained,
simply use this size to define (void *) array.
While on it, change ack_signal type from int to the more
explicit s32 type.
