Subject: net: ipv6: send unsolicited NA on admin up

From: David Ahern <[email protected]>

[ Upstream commit 4a6e3c5def13c91adf2acc613837001f09af3baa ]

ndisc_notify is the ipv6 equivalent to arp_notify. When arp_notify is set to 1, gratuitous arp requests are sent when the device is brought up. The same is expected when ndisc_notify is set to 1 (per ndisc_notify in Documentation/networking/ip-sysctl.txt). The NA is not sent on NETDEV_UP event; add it.
