>Description:
It's possible to trigger a panic by kldload'ing if_tun
if it is already compiled into the kernel or loaded as
a module.
This doesn't happen on 5.4-PRERELEASE systems.
>How-To-Repeat:
kldload if_tun
>Fix:
The following patch works for me, though I'm not sure it's
the correct thing to do.
