We currently dirty a cache line to update tunnel device stats (tx_packets/tx_bytes). We better use the txq->tx_bytes/tx_packets counters that already are present in cpu cache, in the cache line shared with txq->_xmit_lock This patch extends IPTUNNEL_XMIT() macro to use txq pointer provided by the caller. Also &tunnel->dev->stats can be replaced by &dev->stats Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
