Struct RingOffsets 

Source
pub struct RingOffsets {

Expand description

Ring 内存布局偏移(相对于 ring 起始地址)

与内核 xdp_ring_offset 结构一致:

  • producer: 生产者索引的偏移
  • consumer: 消费者索引的偏移
  • desc: 描述符数组起始偏移
  • flags: 标志位偏移
  • len: ring 长度(字节)

Fields§

§producer: u64

生产者索引偏移

§consumer: u64

消费者索引偏移

§desc: u64

描述符数组起始偏移

§flags: u64

标志位偏移

§len: u64

ring 总长度(字节)
