I got this on 4.8-STABLE from July 16 the other day while playing with
dummynet configuration.

I also managed to put tun0 into an unusable state on my firewall
(running ppp(8) with netgraph pppoe on a dsl modem) by using

ipfw pipe 1 bw config tun0

as suggested by the ipfw manpage.

Whereupon nothing at all was transmitted through the pipe even after I
reconfigured it back to the previous (working) setting.  Restarting
ppp, ifconfig down/up, had no effect and I had to reboot the machine
to get it to transmit packets through the interface again.
