Miller" , Eric Dumazet , Jakub Kicinski , Paolo Abeni , Simon Horman , David Ahern , roopa@cumulusnetworks.com, jiri@resnulli.us, stephen@networkplumber.org, jimictw@google.com, prohr@google.com, liuhangbin@gmail.com, nicolas.dichtel@6wind.com, andrew@lunn.ch, netdev@vger.kernel.org, " =?utf-8?q?Maciej_=C5=BBenczykow?= =?utf-8?q?ski?= " , Lorenzo Colitti X-Patchwork-Delegate: dsahern@gmail.com This change adds the following multicast related netlink constants to the UAPI: * RTNLGRP_IPV4_MCADDR and RTNLGRP_IPV6_MCADDR: Netlink multicast groups for IPv4 and IPv6 multicast address changes. * RTM_NEWMULTICAST and RTM_DELMULTICAST: Netlink message types for multicast address additions and deletions. Exposing these constants in the UAPI enables ip monitor to effectively monitor and manage multicast group memberships.
