Adding functionality to libvirt that will allow querying the interface for the availability of switchdev Offloading NIC capabilities. The switchdev mode was introduced in kernel 4.8, the iproute2-devlink command to retrieve the swtichdev NIC feature, Command example: devlink dev eswitch show pci/0000:03:00.0 This feature is needed for Openstack so we can do a scheduling decision if the NIC is in Hardware Offload (switchdev) or regular SR-IOV (legacy) mode.
