Dear Maintainers,
Thanks for the review and suggestions for my patch.
v11 -> v12
----------
- Fix kernel-doc warnings
v10 -> v11
----------
- rename the function ice_set_vf_mac_fn() to __ice_set_vf_mac()
v9 -> v10
--------
- Refactor ice_set_vf_mac() to use reuse the common code blocks
for setting the MAC addresses in both netdev and devlink flow.
v8 -> v9
--------
- Rebasing against dev-queue branch of next-queue tree
v7 -> v8
--------
- Added const keyword for the parameter ``mac`` in ice_set_vf_fn_mac()
v6 -> v7
--------
- Addressed Smatch and checkpatch issues
v5 -> v6
--------
- Changed data type of vf_id to u16
- Used container_of(port, struct ice_vf, devlink_port) to
get the vf instead of ice_get_vf_by_id()/ice_put_vf()
v4 -> v5
--------
- Cloned ice_set_vf_mac() to ice_set_vf_fn_mac() so that the
parameter ice_pf is used instead of net_device of vf
- removed redundant error handling
v3 -> v4
--------
- Released the vf device by calling ice_put_vf()
v2 -> v3
--------
- Fill the extack message instead of dev_err()
v1 -> v2
--------
- called ice_set_vf_mac() directly from the devlink port function
handlers.
RFC -> v1
---------
- Add the function handlers to set and get the HW address for the
VF representor ports.
Changing the MAC address of the VFs is currently unsupported via devlink.
Add the function handlers to set and get the HW address for the VFs.
