vlan: use struct netdev_queue counters instead of dev->stats We can update netdev_queue tx_bytes/tx_packets/tx_dropped counters instead of dev->stats ones, to reduce number of cache lines dirtied in xmit path. This fixes a performance problem on SMP when many different cpus take vlan tx path. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
