Hi,
could someone with more knowledge of the tun device please take a look
at the code around line 387 in net/if_tun.c? It looks like tunoutput()
drops all packets here that aren't of the AF_INET family - most notably,
it drops IPv6 packets.
We hacked around this with the simple fix below, but I'm not sure if
there are any drawbacks...
