Subject: [iwl-next v1 00/15] ice: support devlink subfunctions

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

Patch 1    -> Move devlink port related code to separate file
Patch 2-5  -> Add basic support for devlink subfunctions
Patch 6    -> Expose auxiliary bus devices for subfunctions
Patch 7    -> Expose auxiliary device sfnum attribute in sysfs
Patch 8-13 -> Add eswitch support for subfunctions

Michal Swiatkowski (8):
  ice: store SF data in VSI struct
  ice: store representor ID in bridge port
  ice: create port representor for SF
  ice: check if SF is ready in ethtool ops
  ice: netdevice ops for SF representor
  ice: support subfunction devlink Tx topology
  ice: basic support for VLAN in subfunctions
  ice: move ice_devlink.[ch] to devlink folder

Pawel Chmielewski (1):
  ice: add subfunctions ethtool ops

Piotr Raczynski (6):
  ice: move devlink port code to a separate file
  ice: add new VSI type for subfunctions
  ice: export ice ndo_ops functions
  ice: add basic devlink subfunctions support
  ice: add subfunction aux driver support
  ice: add auxiliary device sfnum attribute
