selftests: fib_tests: Add ipv6 route add append replace tests
Add IPv6 route tests covering add, append and replace permutations.
Assumes the ability to add a basic single path route works; this is
required for example when adding an address to an interface.
$ fib_tests.sh -t ipv6_rt
IPv6 route add / append tests
TEST: Attempt to add duplicate route - gw [ OK ]
TEST: Attempt to add duplicate route - dev only [ OK ]
TEST: Attempt to add duplicate route - reject route [ OK ]
TEST: Add new route for existing prefix (w/o NLM_F_EXCL) [ OK ]
TEST: Append nexthop to existing route - gw [ OK ]
TEST: Append nexthop to existing route - dev only [ OK ]
TEST: Append nexthop to existing route - reject route [ OK ]
TEST: Append nexthop to existing reject route - gw [ OK ]
TEST: Append nexthop to existing reject route - dev only [ OK ]
TEST: Add multipath route [ OK ]
TEST: Attempt to add duplicate multipath route [ OK ]
TEST: Route add with different metrics [ OK ]
TEST: Route delete with metric [ OK ]
IPv6 route replace tests
TEST: Single path with single path [ OK ]
TEST: Single path with multipath [ OK ]
TEST: Single path with reject route [ OK ]
TEST: Single path with single path via multipath attribute [ OK ]
TEST: Invalid nexthop [ OK ]
TEST: Single path - replace of non-existent route [ OK ]
TEST: Multipath with multipath [ OK ]
TEST: Multipath with single path [ OK ]
TEST: Multipath with single path via multipath attribute [ OK ]
TEST: Multipath with reject route [ OK ]
TEST: Multipath - invalid first nexthop [ OK ]
TEST: Multipath - invalid second nexthop [ OK ]
TEST: Multipath - replace of non-existent route [ OK ]
