Network card fault does not only affect the workstation itself, but also often affect the normal operation of the entire network, must arouse the attention of network management personnel. In Ethernet, the network card is used to connect the access media and control the access to the media, and the carrier interception multi-channel access/Conflict detection method (CSMA/CD) adopted by Ethernet is realized in the network card. At the same time, the NIC is also responsible for the upper layer pr
