The quick and dirty way:
Make a clone handler despite the fact that there is no /dev
entry needed. You don't actually have to create a dev entry
in the clone handler, you could just create the gif_interface.
Applications would then:
stat("/dev/gif345") /* Ignore error */
system("ifconfig gif345 bla bla bla");
The slower but less dirty:
Make a sysctl which returns an integer which is the next
free gif device.
The really slow and very dirty:
Implement cloning in ifconfig.
