Hi Ori, and all,

For RSS flow rule, pattern item types and RSS types in action
are an inclusive relationship, and RSS types contain pattern item
types. Is it necessary to set pattern item types when specify RSS
types to create a rule? How should the user set and how should the
driver do?

Looking forward to your reply.

Regards,
Huisong
