Hi, I'm using OFA 1.4.1 and I have a NetEffects RNIC. IP of my RNIC is 192.168.0.1 and IP of my NIC is 10.127.227.60. When I call rdma_resolve_addr for an IP that doesn't exist, like 4.5.7.8, the result state of neigh_lookup is set to NUD_REACHABLE. This happens because after ip_route_output_key is called, rt->rt_gateway is set to 10.127.227.1, while rt->rt_dst is 4.5.7.8 I don't have much knowledge about linux networking but when I use rt->rt_dst instead of rt->rt_gateway, I get the appropriate response. This NUD_REACHABLE state is not a problem for OFA because it checks the gids before calling cma_attach_to_dev, but still, it looks weird to me to get a NUD_REACHABLE state. Do you think it would be a problem if I changed neigh = neigh_lookup(&arp_tbl, &rt->rt_gateway, rt->idev->dev); to neigh = neigh_lookup(&arp_tbl, &rt->rt_dst, rt->idev->dev);
Thanks, Celal
