Subject: [PATCH v3 0/3] vdpa/mlx5: Fix MAC address update via vdpa-tool

This series hardens the mlx5 vDPA MAC plumbing by ensuring new addresses replace old
entries cleanly, reusing shared update logic to keep flow tables consistent, and only
advertising the MAC feature when the device is not yet DRIVER_OK

Changes in v2
 Factor out the MAC address update logic and reuse it from handle_ctrl_mac().
 Address review comments.
Changes in v3
 rename mlx5_vdpa_change_new_mac to mlx5_vdpa_change_mac
 Address review comments.

Cindy Lu (3):
  vdpa/mlx5: update mlx_features with driver state check
  vdpa/mlx5: reuse common function for MAC address updates
  vdpa/mlx5: update MAC address handling in mlx5_vdpa_set_attr()
