[if_tun] Could tunclose remove all kind of routing infos?

[Remi Denis-Courmont]

   Hi,

Is there any reason why, when bringing down a tunnel device, tunclose() from
src/sys/net/if_tun.c only removes routing entries of the AF_INET family? It
seems to be an omission:
There is pretty much the same code in tapclose() from src/sys/net/if_tap.c;
but that one removes all entries, regardless of the address family.

I have problems because of this, as I am using if_tun with IPv6 at the moment,
and the kernel does not cleanup routes when the tunneling program dies (PR
kern/100080). Would there be any problem in removing the "if
(ifa->ifa_addr->sa_family == AF_INET)" line in the TAILQ_FOREACH loop?

Regards,
