| H A D | txrx.c | 1f8bb151 Wed Sep 18 07:43:22 CDT 2013 Michal Kazior <michal.kazior@tieto.com> ath10k: use msdu headroom to store txfrag
Instead of allocating sk_buff for a mere 16-byte
tx fragment list buffer use headroom of the
original msdu sk_buff.
This decreases CPU cache pressure and improves
performance.
Measured improvement on AP135 is 560mbps ->
590mbps of UDP TX briding traffic.
