Web设备收到的目的ip地址非本机且携带ip选项的ip报文后，会将报文上送cpu处理。 CPU解析或处理报文中的IP选项信息后，再根据报文的目的地址进行转发。某些组网环境报文交互量大，设备需要处理或转发的报文数量过多。 WebRaw sockets allow new IPv4 protocols to be implemented in user space. A raw socket receives or sends the raw datagram not including link level headers. The IPv4 layer generates an IP header when sending a packet unless the IP_HDRINCL socket option is enabled on the socket. When it is enabled, the packet must contain an IP header.
