Subject: [PATCH net-next 0/3] devlink: Introduce PCI PF, VF ports and attributes

This patchset carry forwards the work initiated in [1] and discussion
futher concluded at [2].

To improve visibility of representor netdevice, its association with
PF or VF, physical port, two new devlink port flavours are added as
PCI PF and PCI VF ports.

A sample eswitch view can be seen below, which will be futher extended to
mdev subdevices of a PCI function in future.

Patch-1,2 extends devlink port attributes and port flavour.
Patch-3 extends mlx5 driver to register devlink ports for PF, VF and
physical link.
