Attached hosts
allow this config to function:
set int ip address loop0 169.254.1.1/32 (the default GW address for attached hosts)
set int unnumbered af_packet0 use loop0 ('enable' IP on the host interface)
ip route add 192.168.1.1/32 via af_packet0 (where to find the host)
repeat for each host and host interface.
Inter-host communication is throught the /32 routes.
To allow this:
1 - attached host routes have the ATTACHED flag set, so the ARP code accepts then as legitimate sources
2 - unnumbered interfaces inherit the source address from the IP interface
