Netxen is a 10g Nic manufacturer in the United States. It contains its NIC Driver in the Linux kernel source code tree. This article analyzes the data structure and DMA process of the driver, it is hoped that this Nic can be used to achieve zero copy of packets.1. Data Structure 2. Circular Buffer Send the circular buffer: adapter-> pai_buf_arr; Multiple netxen_cmd_buffer structures form a sending ring buffer. After the data packet comes down from the upper layer, it is assigned to a SKB Membe

Buffers are used to improve efficiency, and you must explicitly stream objects before you can use buffers.
