Hi all,

 From following testpmd command:
'flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss types 
ipv4-tcp l3-src-only end queues end / end'
and
"flow create 0 ingress pattern end actions rss types ipv4-tcp 
l3-src-only end queues end / end"

I have some confusions about rte_flow RSS rule:
1> Do pattern item types need to set when configure rte_flow RSS rule?
2> Does the driver need to check and process the pattern? (After all, 
the RSS types in actions alreadly contain all RSS offload types.)

Have someone explains it?

Regards,
Huisong
