Physical write packets processing when posted write error queue is full, with posted write error queue storing physical write requests when posted write packet fails

摘要

A system for handling write requests is described. The system uses two queues for storing posted write requests. When a posted write error results, software handles the posted write error using information stored in a first queue of the two queues. The write request producing the posted write error is cleared from the second queue which continues to handle physical packets containing write requests.
