Thanks for the review. I got it.
Then, how about cleanup by changing return type of
br_handle_ingress_vlan_tunnel()?
This function is only referenced in br_handle_frame(), and goto drop
when it return
non-zero. But, the ingress function always return 0, there is no
meaning for now.
If you think the cleanup is worth it, I'll send you a v2 patch.
