Re: [libvirt] [PATCHv2] nodedev: add switchdev to NIC capabilities

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. And select the appropriate hypervisors with the requested capability see [1].
