ipv4: Cache dst in tunnels Avoid doing a route lookup on every packet being tunneled. In ip_tunnel.c cache the route returned from ip_route_output if the tunnel is "connected" so that all the rouitng parameters are taken from tunnel parms for a packet. Specifically, not NBMA tunnel and tos is from tunnel parms (not inner packet). Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
