Subject: [PATCH RESEND iproute2-next 1/2] iproute2: expose anycast netlink
 constants in UAPI

This change adds the following anycast related netlink constants to
the UAPI:

* RTNLGRP_IPV6_ACADDR: Netlink multicast groups for IPv6 anycast address
  changes.
* RTM_NEWANYCAST and RTM_DELANYCAST: Netlink message types for
  anycast address additions and deletions.
