If there are four tuples (SIP, SPORT, DIP, DPORT), use them to calculate the hash value. Otherwise, use two tuples (SIP, DIP, such as ARP messages) to calculate the hash value, and the algorithm needs to be consistent with the hardware Give the driver an interface with quadruple input and output to obtain the CPU ID value -- This is an automated message from the Apache Git Service.
