devlink: Introduce external controller flag
A devlink eswitch port may represent PCI PF/VF ports of a controller.
A controller either located on same system or it can be an external
controller located in host where such NIC is plugged in.
Add the ability for driver to specify if a port is for external
controller.
Use such flag in the mlx5_core driver.
An example of an external controller having VF1 of PF0 belong to
controller 1.
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev ens2f0pf0vf1 flavour pcivf pfnum 0 vfnum 1 external true splittable false
function:
hw_addr 00:00:00:00:00:00
$ devlink port show pci/0000:06:00.0/2 -jp
