Introduce a new port flavour as virtual so that virtual devices can register 'virtual' flavour to make it more clear to users. An example of one PCI PF and 2 PCI virtual functions, each having one devlink port. $ devlink port show pci/0000:06:00.0/1: type eth netdev ens2f0 flavour physical port 0 pci/0000:06:00.2/1: type eth netdev ens2f2 flavour virtual port 0 pci/0000:06:00.3/1: type eth netdev ens2f3 flavour virtual port 0 Reviewed-by: Jiri Pirko Signed-off-by: Parav Pandit Acked-by: Jakub Kicinski Signed-off-by: David S.
