The issue we encountered is that the network card is in a non-running state but is up. Messages should not be sent out, but the Address Conflict Detection (ACD) function still sends ARP messages. This behavior is incorrect, so we modified the judgment condition. ARP messages can only be sent if the network card is in a running state; otherwise, they cannot be sent. We also simultaneously modified the relevant judgment logic in other business codes to ensure consistency in the judgment of network card status across other businesses @acassis please review it again，Thanks.
