The previous patch added IFA_MC_USERS and emits it for IPv4 multicast groups. Add the same snapshot attribute to IPv6 RTM_GETMULTICAST replies and entry-lifecycle notifications, carrying ifmcaddr6::mca_users. This makes the multicast rtnetlink ABI symmetric across IPv4 and IPv6 and gives userspace the same user count that /proc/net/igmp6 exposes. Signed-off-by: Yuyang Huang <redacted>
