Your driver never seems to block which is different from a "normal" char
device like TUN/TAP, but opening with O_NONBLOCK should fix that
problem. (haven't tried it, though). But then, having a thread that has
to poll that device sounds more like a hack than a clean solution.
Bart's idea seems to scale better, but you've got the advantage that
you've already shown us some code ;-)

That's trivial - just open /dev/net/tun as often as you want. It will
automagically give you a new device every time.
