ipv4: fix forwarding for strict source routes
After the change "Adjust semantics of rt->rt_gateway" (commit f8126f1d51) rt_gateway can be 0 but ip_forward() compares it directly with nexthop. What we want here is to check if traffic is to directly connected nexthop and to fail if using gateway. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.
