Hi, Eric

I confirmed the patch contents again.
For our case, NF_INET_PRE_ROUTING is involved, not NF_BR_LOCAL_IN. 
It seems pre-routing is not included in the patch you mentioned.
BTW, our pkts are all ipv6 DHCP pkts(with MAC 33 33 00 01 00 02).

We verified the patch bellow, and this works fine, no WARN_ON happened.
