SubjectRe: [PATCH 04/12] bridge: netfilter: Use the new global ether_<foo>_addr arrays

This one is already upstream:

https://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git/commit/?id=9124a20d8794663a396b5d6f91f66903848a042b

I can see you're using is_broadcast_ether_addr(e->destmsk) in this new
version, we would need an incremental version.

Thanks.
