摘要：
The invention provides a method for adding specific hardware on both receive and transmit sides that will hide to the software most of the effort related to buffer and pointers management. At initialization, a set of pointers and buffers is provided by software, in quantity large enough to support expected traffic. A Send Queue Replenisher (SQR) and Receive Queue Replenisher (RQR) hide RQ and SQ management to software. RQR and SQR fully monitor pointers queues and perform recirculation of pointers from transmit side to receive side.
