Following Brian's suggestion, I've modified gif to create a /dev/if_gif
device with is controlled by the IOCIFMANAGE ioctl which allows creation
and deletion of specific devices and creation of wildcard devices. I've
hacked ifconfig to support this in a general manner. If you know which
one you want to use you can do something like
ifconfig gif783 10.0.0.1 10.0.0.2
# gifconfig has to come second because I didn't add creation support to
# it because I want to kill it off in favor of ifconfig "tsrc" and
# "tdst" parameters like Solaris uses.
gifconfig gif783 blah
or if you don't care which one you use you can do
newgif=3D`ifconfig gif#`
gifconfig ${newgif} blah=20
ifconfig ${newgif} 10.0.0.1 10.0.0.2
You can also delete interfaces:
ifconfig -D gif783
Additionaly, I removed all the annoying refrences to gif.h and NGIF, and
moved things around so gif can be loaded and unloaded as a module.
A copy of the diff as avaiable at the URL below and I'm submitting a PR
titled "[PATCH] make gif fully dynamic".
