[PATCH 1/2] vdpa/mlx5: Update Control VQ callback information

From: Eli Cohen
Date: Mon Jun 13 2022 - 04:00:37 EST


The control VQ specific information is stored in the dedicated struct
mlx5_control_vq. When the callback is updated through
mlx5_vdpa_set_vq_cb(), make sure to update the control VQ struct.

Fixes: 5262912ef3cf ("vdpa/mlx5: Add support for control VQ and MAC setting")
