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. Refer to examples in patch 13 commit message.
