Hi,
Thanks for the reply.

Yes, it sets skb->pkt_type = PACKET_HOST, but immediately it calls
skb->protocol = eth_type_trans(skb, &br->dev), in eth_type_trans,
if (*eth->h_dest&1) {
/* if (memcmp()), otherwise MULTI */
skb->pkt_type = PACKET_BROADCAST;
}
So, I am not sure, what happens exactly, b'coz there are 2 functions , get
called skb_pull() (in eth.c::eth_type_trans) and skb_push() (in
br_input.c::br_pass_frame_up). One of these functions, change skb->mac to
'bridge' device mac ?
Please let me know.
Many Thanks,
