Rtnetlink dump handlers are invoked when the user is requesting a dump of a kernel object database (links, routes, fdb, neigh). We discuss Rtnetlink dumps in the context of short lived and long running networking applications:

WebEach netlink family has a set of 32 multicast groups. When bind (2) is called on the socket, the nl_groups field in the sockaddr_nl should be set to a bit mask of the groups which it wishes to listen to. The default value for this field is zero which means that no multicasts will be received.
Webunicast instead of multicast. By default this flag is off. This is done by copying the packet per host and changing the multicast destination MAC to a unicast one accordingly. mcast_to_unicast works on top of the multicast snooping feature of the bridge.
