Implement the get_vq_stats calback of vdpa_config_ops to return the statistics for a virtqueue. The statistics are provided as vendor specific statistics where the driver provides a pair of attribute name and attribute value. Currently supported are received descriptors and completed descriptors. Signed-off-by: Eli Cohen <elic@nvidia.com> Message-Id: <20220518133804.1075129-6-elic@nvidia.com> Signed-off-by: Michael S.
