[PATCH net v2 0/2] ipv6: ignore link state in gateway check

[Yaroslav Dudkov]

IPv6 gateway validation can reject routes in non-main tables when
ignore_routes_with_linkdown is enabled and the nexthop device has
no carrier, even though these routes should be added.

Fix this by ignoring link state during gateway validation and add a
regression selftest covering IPv4 and IPv6 route installation.

Changes in v2:
- Fix variable ordering.
- Add a regression selftest.
