A DDP > package is loaded by the driver during probe time. The DDP package programs > functionality in both the parser and switching blocks in the pipeline, allowing > dynamic support for new and existing protocols. > Once the pipeline is configured, the driver can identify the protocol and apply any > HW action in different stages, for example, direct packets to desired hardware > queues (flow director), queue groups or drop. > > Patches 1-8 introduce a DDP package parser API that enables different pipeline > stages in the driver to learn the HW parser capabilities from the DDP package > that is downloaded to HW. The parser library takes raw packet patterns and > masks (in binary) indicating the packet protocol fields to be matched and > generates the final HW profiles that can be applied at the required stage. With > this API, raw flow filtering for FDIR or RSS could be done on new protocols or > headers without any driver or Kernel updates (only need to update the DDP > package). These patches were submitted before [1] but were not accepted > mainly due to lack of a user. > > Patches 9-11 extend the virtchnl support to allow the VF to request raw flow > director filters. Upon receiving the raw FDIR filter request, the PF driver allocates > and runs a parser lib instance and generates the hardware profile definitions > required to program the FDIR stage. These were also submitted before [2]. > > Finally, patches 12 and 13 add TC U32 filter support to the iavf driver. > Using the parser API, the ice driver runs the raw patterns sent by the user and > then adds a new profile to the FDIR stage associated with the VF's VSI.
