Fixes: 1cbe6fc86ccfe ("IB/mlx5: Add support for CQE compressing") Fixes: fed9ce22bf8ae ("net/mlx5: E-Switch, Add API to create vport rx rules") Fixes: 9efa75254593d ("net/mlx5_core: Introduce access functions to query vport RoCE fields") Signed-off-by: Christophe JAILLET --- v1 -> v2: More places to update have been added to the patch v2 -> v3: Add Fixes tag 3 patches with one Fixes tag each should probably be better, but honestly, I won't send a v4.
