It is printed to stdout. Since status is not printed on creation, it is
the only thing on stdout so it is easy to hand in a script:
newgif=`ifconfig gif# create`
ifconfig $newgif 10.0.0.1 10.0.0.2
For programmers, notification is done by modifying the name in the ifreq
used to create the new interface.
