The only way to have more hardware backed netdev is to use SR-IOV. Following patchset adds support for devlink port API. For each new pcisf type port, driver allocates new VSI, configures all resources needed, including dynamically MSIX vectors, program rules and registers new netdev. This series supports only one Tx/Rx queue pair per subfunction. Example commands: devlink port add pci/0000:31:00.1 flavour pcisf pfnum 1 sfnum 1000 devlink port function set pci/0000:31:00.1/1 hw_addr 00:00:00:00:03:14 devlink port function set pci/0000:31:00.1/1 state active devlink port function del pci/0000:31:00.1/1 Make the port representor and eswitch code generic to support subfunction representor type. VSI configuration is slightly different between VF and SF. It needs to be reflected in the code. --- v4: - fix dev warn message when index isn't supported - change pf->hw.bus.func to internal pf id - use devl_register instead of locking version - rephrase last commit message v3: https://lore.kernel.org/netdev/20240808173104.385094-1-anthony.l.nguyen@intel.com/ - move active checking into functions where it is set - move devlink port creation for subfunction into patchset where it is used - change error message in subfunction activation to be consistent - remove leftover from patch 5 (sorry Simon that I missed your comment previously) - add support for xsk ZC multi-buffer for subfunction netdev v2: https://lore.kernel.org/netdev/20240731221028.965449-1-anthony.l.nguyen@intel.com/ - Add more recipients v1: https://lore.kernel.org/netdev/20240729223431.681842-1-anthony.l.nguyen@intel.com/ iwl-next: https://lore.kernel.org/intel-wired-lan/20240606112503.1939759-1-michal.swiatkowski@linux.intel.com/ The following are changes since commit dd1bf9f9df156b43e5122f90d97ac3f59a1a5621: net: hinic: use ethtool_sprintf/puts and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE Michal Swiatkowski (8): ice: treat subfunction VSI the same as PF VSI ice: make representor code generic ice: create port representor for SF ice: don't set target VSI for subfunction ice: check if SF is ready in ethtool ops ice: implement netdevice ops for SF representor ice: support subfunction devlink Tx topology ice: basic support for VLAN in subfunctions Piotr Raczynski (7): ice: add new VSI type for subfunctions ice: export ice ndo_ops functions ice: add basic devlink subfunctions support ice: allocate devlink for subfunction ice: base subfunction aux driver ice: implement netdev for subfunction ice: subfunction activation and base devlink ops drivers/net/ethernet/intel/ice/Makefile | 2 + .../net/ethernet/intel/ice/devlink/devlink.c | 46 ++ .../net/ethernet/intel/ice/devlink/devlink.h | 1 + .../ethernet/intel/ice/devlink/devlink_port.c | 508 +++++++++++++++++- .../ethernet/intel/ice/devlink/devlink_port.h | 46 ++ drivers/net/ethernet/intel/ice/ice.h | 19 +- drivers/net/ethernet/intel/ice/ice_base.c | 5 +- drivers/net/ethernet/intel/ice/ice_dcb_lib.c | 1 + drivers/net/ethernet/intel/ice/ice_eswitch.c | 111 +++- drivers/net/ethernet/intel/ice/ice_eswitch.h | 22 +- drivers/net/ethernet/intel/ice/ice_ethtool.c | 7 +- drivers/net/ethernet/intel/ice/ice_lib.c | 52 +- drivers/net/ethernet/intel/ice/ice_lib.h | 3 + drivers/net/ethernet/intel/ice/ice_main.c | 66 ++- drivers/net/ethernet/intel/ice/ice_repr.c | 211 ++++++-- drivers/net/ethernet/intel/ice/ice_repr.h | 22 +- drivers/net/ethernet/intel/ice/ice_sf_eth.c | 329 ++++++++++++ drivers/net/ethernet/intel/ice/ice_sf_eth.h | 33 ++ .../ethernet/intel/ice/ice_sf_vsi_vlan_ops.c | 21 + .../ethernet/intel/ice/ice_sf_vsi_vlan_ops.h | 13 + drivers/net/ethernet/intel/ice/ice_sriov.c | 4 +- drivers/net/ethernet/intel/ice/ice_txrx.c | 2 +- drivers/net/ethernet/intel/ice/ice_type.h | 1 + drivers/net/ethernet/intel/ice/ice_vf_lib.c | 4 +- .../net/ethernet/intel/ice/ice_vsi_vlan_ops.c | 4 + drivers/net/ethernet/intel/ice/ice_xsk.c | 2 +- 26 files changed, 1397 insertions(+), 138 deletions(-) create mode 100644 drivers/net/ethernet/intel/ice/ice_sf_eth.c create mode 100644 drivers/net/ethernet/intel/ice/ice_sf_eth.h create mode 100644 drivers/net/ethernet/intel/ice/ice_sf_vsi_vlan_ops.c create mode 100644 drivers/net/ethernet/intel/ice/ice_sf_vsi_vlan_ops.h
