From 1892a3d425bf525ac98d6d3534035e6ed2bfab50 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Wed, 18 May 2022 16:38:03 +0300 Subject: vdpa/mlx5: Add support for reading descriptor statistics 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 Message-Id: <20220518133804.1075129-6-elic@nvidia.com> Signed-off-by: Michael S.
