And speaking of DHCP, do you (or anyone else) know, whether a
dhcp-server (or its kernel) sends an ARP request before sending
a unicast DHCPOFFER? Or do dhcp-servers usually craft DHCPOFFERs
in userspace within their daemon including the ethernet header?
If the latter is the case, maybe we could/should dat-snoop the
ethernet+IP destination of such DHCPOFFERs in interface_rx(),
too?
