Yes, ifconfig shows PROMISC for the interfaces.  I neglected to mention 
before that I already know the packets are being picked up... I get a 
response when I ping the virtual host, but I get a duplicate response as 
well... from the host in the backup state.

That call is what I was looking for... from what I understand now, 
ifp->if_input is set to ether_input in ether_ifattach, so essentially 
the driver does call ether_input.  Hi ho, hi ho, back to the drawing 
board I go.
