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.
