Subject: [PATCH v4 net-next 0/8] sfc: devlink support for ef100

From: Alejandro Lucero <alejandro.lucero-palau@....com>

v4 changes:
 - Add new doc file to MAINTAINERS
 - nvram metadata call independent of MTD config
 - add more useful info with extack

v3 changes:
 - fix compilation warnings/errors reported by checkpatch

v2 changes:
 - splitting up devlink info from basic devlink support
 - using devlink lock/unlock during initialization and removal
 - fix devlink registration order
 - splitting up efx_devlink_info_running_versions
 - Add sfc.rst with specifics about sfc info
 - embedding dl_port in mports
 - using extack for error reports to user space

This patchset adds devlink port support for ef100 allowing setting VFs
mac addresses through the VF representor devlink ports.

Basic devlink infrastructure is first introduced, then support for info
command. Next changes for enumerating MAE ports which will be used for
devlink port creation when netdevs are registered.

Adding support for devlink port_function_hw_addr_get requires changes in
the ef100 driver for getting the mac address based on a client handle.
This allows to obtain VFs mac addresses during netdev initialization as
well what is included in patch 6.

Such client handle is used in patches 7 and 8 for getting and setting
devlink port addresses.

Alejandro Lucero (8):
  sfc: add devlink support for ef100
  sfc: add devlink info support for ef100
  sfc: enumerate mports in ef100
  sfc: add mport lookup based on driver's mport data
  sfc: add devlink port support for ef100
  sfc: obtain device mac address based on firmware handle for ef100
  sfc: add support for devlink port_function_hw_addr_get in ef100
  sfc: add support for devlink port_function_hw_addr_set in ef100
