Method and apparatus for receive frame sorting in a media access control/host system interface unit

An interface system connected between a local area network communications medium and a network station for transferring information between the communications medium and a memory system associated with the network station, the interface system comprising:

• a bus interface unit connectable to the network station for transferring information between the interface system and the memory system;
• an indicate mechanism connected to the bus interface unit for transferring information received by the interface system from the communications medium to the memory system via the bus interface unit;
• a request mechanism connected to the bus interface unit for transferring information received by the interface system from the memory system via the bus interface unit to the communications medium;
• and
• a management mechanism, connected to the indicate mechanism, that manages the allocation of storage space in the memory system for information transferred between the communications medium and the interface system;
• a plurality of receive channels for connection between the bus interface unit and the memory system;
• for each receive channel, an associated pool space descriptor queue connected to said receive channel for storing destination information that indicates where frame data information transferred from the communications medium to the memory system via said receive channel is to be stored in the memory system;
• and
• for each receive channel, an associated status queue connected to said receive channel for storing status information related to information transferred from the communications medium to the memory system via said receive channel.
