Abstract
A mechanism for mitigating the rate at which status reports associated with raw cell data transfers occur during receive operations in a network node is presented. The network node has an adapter for coupling a network and a host system, the host system including a host memory. The adapter operates to reassemble cell data received from the network and store the reassembled cell data in the host memory. A raw report holdoff counter is programmed to count a number corresponding to a preselected rx raw report holdoff value. If a raw cell data transfer request to be processed is detected, rx raw report information necessary to creating an rx raw cell status report is copied to a temporary storage area. When the data is transferred to the host system, the raw report holdoff counter is modified by one. When the modified counter has expired, the rx raw report information is written to a report queue in host memory.
