A SF netdev supports E-Switch representation\noffload similar to existing PF and VF representors. A SF shares PCI\nlevel resources with other SFs and/or with its parent PCI function.\n\nFrom SmartNIC perspective, when PCI device is shared for multi-host,\nrepresentors for host controller and host PF is required.\n\nThis patch set introduces new representor types in addtion to existing\nVF representor.
