When you redirect a VLAN device to any device, you end up with crap in af_packet on the xmit path because hard_header_len is not equal to skb->mac_len. So the redirected packet contains four extra bytes at the start which then gets interpreted as part of the MAC address. This patch fixes this by only pushing skb->mac_len. We also need to fix ifb because it tries to undo the pushing done by act_mirred. Signed-off-by: Herbert Xu <[email protected]> Acked-by: Alexei Starovoitov <[email protected]> Signed-off-by: David S.
