We poll the network interface anytime we enter the network driver (typically for transmitting a packet) and from the process scheduler's idle loop.

一旦进入网络驱动(通常是传输一个数据包时)以及在进程调度器的空闲循环的时候，对网络接口进行轮询。

Final tested to prove the network device driver can be a very good realization of the network packet data transmission, to achieve a relatively rapid speed and high stability.

最后测试证明此网络设备驱动能够很好地实现网络包数据的传输，达到了较快的速度和较高的稳定性。

At the same time reduced a net card driver to the user space duplication network data packet system call.

同时减少了一次网卡驱动程序向用户空间复制网络数据包的系统调用。
