Almost all of iproute2 is based on netlink, I don't want to add non netlink
interfaces. 

So you want to add a new interface to the kernel which duplicates the
one we've had for years, then make userspace which will only work with
newer kernels?

I agree, Stephen just put in the ioctl() or whatever based support
for TUN devices.  We've done stuff like this before in iproute2
so your arguments against this are hogwash.
