Hmm, I guess it is because the offset used by u32 filter is no longer accurate when vlan tag is inserted into mac header. On egress side, skb->data points to the mac header, so the offset of IP header is different when vlan tag is involved. Did this really work before? I don't follow vlan changes, it seems it has been already like this for a long time.
