xen-netfront: be more drop monitor friendly
xennet_start_xmit() might copy skb with inappropriate layout into a fresh one. Old skb is freed, and at this point it is not a drop, but a consume. New skb will then be either consumed or dropped. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
