ipv6: Change rt6_probe to take a fib6_nh
rt6_probe sends probes for gateways in a nexthop. As such it really depends on a fib6_nh, not a fib entry. Move last_probe to fib6_nh and update rt6_probe to a fib6_nh struct. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
