History
Gleb Smirnoff 25af0bb50e Add some initial locking to gif(4). It doesn't covers the whole driver, 
however IPv4-in-IPv4 tunnels are now stable on SMP. Details:

- Add per-softc mutex.
- Hold the mutex on output.

The main problem was the rtentry, placed in softc. It could be
freed by ip_output(). Meanwhile, another thread being in
in_gif_output() can read and write this rtentry.
