Important changes from previous version: * remove unnecessary checks for devlink port type * link correct devlink port to subfunction netdev Follow up patchset with subfunction port representor will be the last patchset for subfunction implementation in ice. It is a little unpleasant to split it like that, because devlink port should be linked with port representor netdev. In this patchset use devlink port without linking it. It will be done correctly in the follow up when subfunction port representor is available. Currently ice driver does not allow creating more than one networking device per physical function. 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 [1] https://lore.kernel.org/netdev/20240301115414.502097-1-michal.swiatkowski@linux.intel.com/ 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: allow to activate and deactivate subfunction drivers/net/ethernet/intel/ice/Makefile | 1 + .../net/ethernet/intel/ice/devlink/devlink.c | 42 +- .../net/ethernet/intel/ice/devlink/devlink.h | 1 + .../ethernet/intel/ice/devlink/devlink_port.c | 512 ++++++++++++++++++ .../ethernet/intel/ice/devlink/devlink_port.h | 37 ++ drivers/net/ethernet/intel/ice/ice.h | 12 + 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_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_sf_eth.c | 317 +++++++++++ drivers/net/ethernet/intel/ice/ice_sf_eth.h | 33 ++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + drivers/net/ethernet/intel/ice/ice_xsk.c | 2 +- 15 files changed, 1039 insertions(+), 46 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
