ipv6: add knob to send unsolicited ND on link-layer address change
This patch introduces a new knob ndisc_notify. If enabled, the kernel will transmit an unsolicited neighbour advertisement on link-layer address change to update the neighbour tables of the corresponding hosts more quickly. This is the equivalent to arp_notify in ipv4 world. Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S. Miller <davem@davemloft.net>
