Patrick McHardy 4277a083ec [NETLINK]: Add netlink_has_listeners for avoiding unneccessary event message generation ... Keep a bitmask of multicast groups with subscribed listeners to let netlink users check for listeners before generating multicast messages. Queries don't perform any locking, which may result in false positives, it is guaranteed however that any new subscriptions are visible before bind() or setsockopt() return.
