libvirt can retrieve traffic stats for emulated interfaces that are backed by tap or macvtap devices, but this information wasn't available for hostdev interfaces (those that are implemented by assigning an SR-IOV VF device to a guest using vfio): #virsh domifstat instance --interface=52:54:00:2d:b2:35 error: Failed to get interface stats instance 52:54:00:2d:b2:35 error: internal error: Interface name not provided For some SR-IOV VF devices this information is available via the netlink VFINFO_LIST request/response, and that is what this patch uses to implement stats retrieval for VF. Not that this is dependent on support in the PF driver - for example, the Mellanox ConnectX-4 Lx (mlx5) driver reports usable stats, while Intel 82599 (ixgbe) and 82576 (igb) just report all stats as 0. (this is the same result as "ip -s link show"). Signed-off-by: zhenwei pi <pizhenwei@bytedance.com> Reviewed-by: Laine Stump <laine@redhat.com>
