H A D | txrx.c | 6942726f Sun Mar 06 08:14:30 CST 2016 Michal Kazior <michal.kazior@tieto.com> ath10k: add fast peer_map lookup
The pull-push functionality of 10.4 will be based on peer_id and tid. These will need to be mapped, eventually, to ieee80211_txq to be used with ieee80211_tx_dequeue().
Iterating over existing stations every time peer_id needs to be mapped to a station would be inefficient wrt CPU time.
The new firmware, which will be the only user of the code flow-wise, will guarantee to use low peer_ids first so despite peer_map's apparent huge size d-cache thrashing should not be a problem.
Older firmware hot paths will effectively not use peer_map.
