is
relevant for only one address family.
The patch determines whether the applicable address family is AF_INET6
instead of the default AF_INET and makes the "-6" option unnecessary for
"ip tunnel add".

* vti and vti6 tunnel modes added to ip-tunnel.8 manual page
* Added hoplimit terminology for IPv6
* Corrected usage line
* Minor language fix

The DF bit on IPv4 GRE tunnels with fixed TTL is enforced in order
to prevent networking loops. This was the original behavior of GRE
tunnels, lost in the refactoring.

c54419321455631 removed this enforcing from GRE tunnels,
not changing this behavior for IP-IP (net/ipv4/ipip.c) and SIT
(net/ipv6/sit.c).
It can be discussed whether such enforcing of DF bit is exactly the
desired behavior, but shouldn't it at least be identical across IPv4
tunnels?
