Subject: [PATCH net-next v2 0/6] Adding permanent config get/set to devlink

Changes since v1, based on the excellent feedback received:

* Implemented nested parameters correctly this time, I think.
* Submitting config get/set infrastructure separately from the
  parameters themselves, and then submitting just the first four
  parameters as separate patches.  Once this approach is
  accepted, I will add additional parameters, taking into
  account comments received on them.
* Changed devlink_nl_sing_param_get/set to use _single_.
* Tried to make clear that all params using this command are
  permanent / NVRAM settings, not transient.
* Split out the reorganization of bnxt driver to separate patch,
  submitted to net-next earlier today.
* One non-change: The devices this change affects don't typically
  have a separate 'asic' pci b/d/f versus per-port b/d/f; they
  just have (typically multiple) b/d/f entities for each function
  on the device.  So, doesn't seem to me like splitting these
  parameters into port vs.  device params works here.

Adds a devlink command for getting & setting permanent
(persistent / NVRAM) device configuration parameters, and
enumerates the parameters as nested devlink attributes.

bnxt driver patch makes use of these new devlink cmds.

Steve Lin (6):
  devlink: Add permanent config parameter get/set operations
  devlink: Adding SR-IOV enablement NVRAM config param
  devlink: Adding num VFs per PF NVRAM config param
  devlink: Adding max PF MSI-X vectors NVRAM config param
  devlink: Adding num MSI-X vectors per VF NVRAM config param
  bnxt: Add devlink support for config get/set
