Hi, Thomas, we make use of the API for rte_raw to achieve our protocol agnostic
flow offloading method, including RSS and FDIR. Behind it is the new Parser
Library feature based on DDP, rather than the original logic I think.
Binary-format pattern spec and mask are passed to Parser Library and the
corresponding protocol ID and offset will be provided.
