[ Upstream commit 7973d9e76727aa42f0824f5569e96248a572d50b ]
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.
