That should work fine for VLAN, but not for loopback since its

because it doesn't require to change all the other existing
packet_type users.
I think Al's idea is the most elegant proposed so far and we could do
something similar on the TX side as well.
Yes, it means diddling with a lot of call sites, but we do that all
the time and it's heaps better then these "check the stack space
remaining" hacks being proposed.
Agreed on second thought, I guess I was just being lazy :)
