Add basic flow steering. For now, we support IPv4 and TCP/UDP only. Patch 1 renames "enum virtchnl2_cap_rss" to a more generic "enum virtchnl2_flow_types" that can be used with RSS and flow steering.
Patch 2 adds the required flow steering virtchnl2 OP codes and patch 3 adds the required flow steering ethtool ntuple ops to the idpf driver. --- v2: - Rename "enum virtchnl2_cap_rss" to virtchnl2_flow_types in a separate patch (Patch 1). - Change comments of freed BIT(6, 13) in patch 2 (Tony). - Remove extra lines before VIRTCHNL2_CHECK_STRUCT_LEN (this makes checkpatch complaints, but Tony believes this is preferred. - Expand commit of patch 3 (Sridhar). - Fix lkp build error (patch 3). - Move 'include "idpf_virtchnl.h"' from idpf.h to idpf_ethtool.c (patch 3) (Olek). - Expand the cover letter text (Olek). - Fix kdocs warnings. v1: - https://lore.kernel.org/netdev/20250324134939.253647-1-ahmed.z...@intel.com/ Ahmed Zaki (2): virtchnl2: rename enum virtchnl2_cap_rss idpf: add flow steering support Sudheer Mogilappagari (1): virtchnl2: add flow steering support drivers/net/ethernet/intel/idpf/idpf.h | 33 +- .../net/ethernet/intel/idpf/idpf_ethtool.c | 298 +++++++++++++++++- drivers/net/ethernet/intel/idpf/idpf_lib.c | 5 + .../net/ethernet/intel/idpf/idpf_virtchnl.c | 121 ++++++- .../net/ethernet/intel/idpf/idpf_virtchnl.h | 6 + drivers/net/ethernet/intel/idpf/virtchnl2.h | 249 +++++++++++++-- 6 files changed, 666 insertions(+), 46 deletions(-) -- 2.43.0
