Look at: http://people.freebsd.org/~bms/dump/nifconfig/nifconfig-design.txt

There is a pending change to if_gre to enable it to be easily classified
in this way; ifconfig would simply query the interface for its if_type. This
is one way to do it without having to change struct ifnet. We could add a
new field, but avoiding changing the ABI is a Good Thing.
