Yes, it does. :) I would see this at some point but CCing me speed things up 
quite a lot.

Yes, this is necessary.  We are doing ARP filtering according to the IP address 
of the interface, as you have realized.  Our implementation is rather ugly at 
the moment, so the plan is to try to get rid of this dependency on INET, but we 
need it for now.

Thanks Randy for finding this and thanks John for fixing it.
