 all the test cases run the same test steps as below:
 
 1. validate rule.
-2. send hit pattern packets with switched value of input set in the rule.
+2. if the rule is MAC_IPV4_UDP/TCP/SCTP or MAC_IPV6_UDP/TCP/SCTP,
+   set "port config all rss all".
+3. send hit pattern packets with switched value of input set in the rule.
    check the received packets have different hash value.
    check all the packets are distributed to queues by rss.
