As some driver authors seem to reintroduce dev->last_rx use, add a comment to strongly discourage this. Since commit 6cf3f41e6c0 (bonding, net: Move last_rx update into bonding recv logic), network drivers dont need to update last_rx themselves, unless they use this field to implement a timeout. Not updating last_rx helps not dirtying a cache line, improving performance in SMP. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net> |
