This patch adds the following functions to get PF/VF relationship of an SRIOV network interface: ifaceIsVirtualFunction: Function to check if a network interface is a SRIOV VF ifaceGetVirtualFunctionIndex: Function to get VF index if a network interface is a SRIOV VF ifaceGetPhysicalFunction: Function to get the PF net interface name of a SRIOV VF net interface Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com>
