		struct tipc_port_list *	dports
	)

tipc_nametbl_mc_translate - find multicast destinations

Creates list of all local ports that overlap the given multicast address; also determines if any off-node ports overlap.

Note: Publications with a scope narrower than 'limit' are ignored. (i.e. local node-scope publications mustn't receive messages arriving from another node, even if the multcast link brought it here)

Returns non-zero if any off-node ports overlap

tipc_nametbl_translate - perform name translation

On entry, 'destnode' is the search domain used during translation.

On exit:

• if name translation is deferred to another node/cluster/zone, leaves 'destnode' unchanged (will be non-zero) and returns 0
• if name translation is attempted and succeeds, sets 'destnode' to publishing node and returns port reference (will be non-zero)
• if name translation is attempted and fails, sets 'destnode' to 0 and returns 0
