The information passed in a bind request is a function of the type of packets to be handled by this stream--Ethernet, 802.2, or IPX. In all three cases, the dl_max_conind field should be set to 0 and the dl_service_mode field must be set to the constant DL_CLDLS.
Note
The DLPI specification leaves open the possibility that several streams on the same hardware port could be bound to a single DLSAP. This feature is explicitly supported by the Open Transport CSMA/CD driver. If a packet arrives addressed to two or more streams simultaneously, each stream receives a copy of the packet.
