Description

Hi,

Playing around with vknet(1) where some tap devices were created, I destroy one
of them with 'ifconfig tap0 destroy' and after some time I got the panic below.
I don't have a way to reproduce it yet, but I got a dump.

The core.txt file is here:
http://leaf.dragonflybsd.org/~tuxillo/archive/temp/core_ifq.6.txt

I will upload the core to leaf by request.

Cheers,
Antonio Huete
