Are you going to add such code to RAW, UDP, TCP, etc. etc.?

I understand the problem, but the point I'm making here is that
I see nothing which makes it specific to AF_PACKET.

This brings us back to an old and sore topic, which is the
dst_dev_event() code in net/core/dst.c, have you had a look
at that?
