Subject: [PATCH iproute2-next 3/3] devlink: Expose port split ability

Add a new attribute that indicates the port split ability to devlink port.

Expose the attribute to user space as RO value, for example:

$devlink port show swp1
pci/0000:03:00.0/61: type eth netdev swp1 flavour physical port 1
splittable false lanes 1
