Thanks for your review.
We can not contain all the RSS offload types. We need i40e_filter_pctype to configure the queue region. It only defines some basic pctypes and there is no regular between i40e_filter_pctype and RSS offload types. So for "flow create", it can only configure queue region for these basic pctypes. What we can do is associate them with RSS offload types.

Thanks.
Shougang
