Use ping -r to test the kernel behaviour with raw and ping sockets
having the SO_DONTROUTE option.
Since ipv4_ping_novrf() is called with different values of
net.ipv4.ping_group_range, then it tests both raw and ping sockets
(ping uses ping sockets if its user ID belongs to ping_group_range
and raw sockets otherwise).
With both socket types, sending packets to a neighbour (on link) host,
should work. When the host is behind a router, sending should fail.
