Konstantin Shkolnyy 0d508cefcd vdpa/mlx5: Fix mlx5_vdpa_get_config() endianness on big-endian machines ... [ Upstream commit 439252e167 ] mlx5_vdpa_dev_add() doesn’t initialize mvdev->actual_features. It’s initialized later by mlx5_vdpa_set_driver_features(). However, mlx5_vdpa_get_config() depends on the VIRTIO_F_VERSION_1 flag in actual_features, to return data with correct endianness. When it’s called before mlx5_vdpa_set_driver_features(), the data are incorrectly returned as big-endian on big-endian machines, while QEMU then interprets them as little-endian. The fix is to initialize this VIRTIO_F_VERSION_1 as early as possible, especially considering that mlx5_vdpa_dev_add() insists on this flag to always be set anyway.
