ipv6: Return error for RTA_VIA attribute
IPv6 currently does not support nexthops outside of the AF_INET6 family.
Specifically, it does not handle RTA_VIA attribute. If it is passed
in a route add request, the actual route added only uses the device
which is clearly not what the user intended:
$ ip -6 ro add 2001:db8:2::/64 via inet 172.16.1.1 dev eth0
$ ip ro ls
...
2001:db8:2::/64 dev eth0 metric 1024 pref medium
Catch this and fail the route add:
$ ip -6 ro add 2001:db8:2::/64 via inet 172.16.1.1 dev eth0
Error: IPv6 does not support RTA_VIA attribute.
