Abrégé

An RNIC implementation that performs direct data placement to memory where all
segments of a particular connection are aligned, or moves data through
reassembly buffers where all segments of a particular connection are non-
aligned. The type of connection that cuts-through without accessing the
reassembly buffers is referred to as a "Fast" connection because it is highly
likely to be aligned, while the other type is referred to as a "Slow"
connection. When a consumer establishes a connection, it specifies a
connection type (S2). The connection type can change from Fast to Slow and
back. The invention reduces memory bandwidth, latency, error recovery using
TCP retransmit and provides for a "graceful recovery" from an empty receive
queue. The implementation also may conduct CRC validation (S11, S6) for a
majority of inbound DDP segments in the Fast connection before sending a TCP
acknowledgement (Ack) confirming segment reception.
