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 i= s 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
