Hi Dave,

I am handling maintenance of the nfp diver in Jakub's absence while he is
on vacation this week and next, and I am sending this patchset in that
capacity.

Regarding the patches, Dirk says:

This series adds configuration capabilities to the firmware loading policy of
the NFP driver.

NFP firmware loading is controlled via three HWinfo keys which can be set per
device: 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'.
Refer to patch #11 for more detail on how these control the firmware loading.

In order to configure the full extend of FW loading policy, a new devlink
parameter has been introduced, 'reset_dev_on_drv_probe', which controls if the
driver should reset the device when it's probed. This, inconjunction with the
existing 'fw_load_policy' (extended to include a 'disk' option) provides the
means to tweak the NFP HWinfo keys as required by users.

Patches 1 and 2 adds the devlink modifications and patches 3 through 9 adds the
support into the NFP driver. Furthermore, the last 2 patches are documentation
only.

Dirk van der Merwe (11):
  devlink: extend 'fw_load_policy' values
  devlink: add 'reset_dev_on_drv_probe' param
  nfp: nsp: add support for fw_loaded command
  nfp: nsp: add support for optional hwinfo lookup
  nfp: nsp: add support for hwinfo set operation
  nfp: honor FW reset and loading policies
  nfp: add devlink param infrastructure
  nfp: devlink: add 'fw_load_policy' support
  nfp: devlink: add 'reset_dev_on_drv_probe' support
  kdoc: fix nfp_fw_load documentation
  Documentation: nfp: add nfp driver specific notes
