Hi,
Can someone tell me the difference between the IFF_UP and IFF_RUNNING
flags ?
Currently, the tun pseudo-device never bothers removing the RUNNING
flag. This can easily be fixed with

+ ifp->if_flags &= ~IFF_RUNNING;

funsetown(tp->tun_sigio);
selwakeup(&tp->tun_rsel);
But is this the right fix ? Should IFF_RUNNING be removed with the
last address - for *all* interfaces ?
Cheers.
