mlxsw: spectrum_router: Fix IPv4 nexthop gateway indication
mlxsw needs to distinguish nexthops with a gateway from connected nexthops in order to write the former to the adjacency table of the device. The check used to rely on the fact that nexthops with a gateway have a 'link' scope whereas connected nexthops have a 'host' scope. This is no longer correct after commit 747c14307214 ("ip: fix dflt addr selection for connected nexthop"). Fix that by instead checking the address family of the gateway IP. This is a more direct way and also consistent with the IPv6 counterpart in mlxsw_sp_rt6_is_gateway(). Cc: stable@vger.kernel.org Fixes: 747c14307214 ("ip: fix dflt addr selection for connected nexthop") Fixes: 597cfe4fc339 ("nexthop: Add support for IPv4 nexthops") Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Amit Cohen <amcohen@nvidia.com> Reviewed-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.
