However, we don't have to validate backup slaves if arp_validate == active and vice versa, so return early in bond_arp_rcv() in these cases. It works correctly now because we verify arp_validate in slave_last_rx(), however we're just doing useless work in bond_arp_rcv(). Signed-off-by: Veaceslav Falico Signed-off-by: David S.
