Additionally priv data entry for the rep is not passed during registration, but its copied. It is used (set and cleared) by the user of the reps. As we want to scale vports, to simplify and also to split constants from data, 1. Rename mlx5_eswitch_rep_if to mlx5_eswitch_rep_ops as to match _ops prefix with other standard netdev, ibdev ops. 2. Constify the IB and Ethernet rep ops structure. 3. Instead of storing copy of all rep function pointers, store copy per eswitch rep type. 4. Split data and function pointers to mlx5_eswitch_rep_ops and mlx5_eswitch_rep_data.
