mlxsw: spectrum_router: Prevent ipv6 gateway with v4 route via replace and append
mlxsw currently does not support v6 gateways with v4 routes. Commit
19a9d136f198 ("ipv4: Flag fib_info with a fib_nh using IPv6 gateway")
prevents a route from being added, but nothing stops the replace or
append. Add a catch for them too.
$ ip ro add 172.16.2.0/24 via 10.99.1.2
$ ip ro replace 172.16.2.0/24 via inet6 fe80::202:ff:fe00:b dev swp1s0
Error: mlxsw_spectrum: IPv6 gateway with IPv4 route is not supported.
$ ip ro append 172.16.2.0/24 via inet6 fe80::202:ff:fe00:b dev swp1s0
Error: mlxsw_spectrum: IPv6 gateway with IPv4 route is not supported.
