We don't need to advertise counters for feature that is not supported. In multiport mlx5 devices, the reload functionality is not supported, so this change at least make that device to behave like all other netdev devices that don't support devlink reload. The ops structure is set very early to make sure that internal devlink routines will be able access driver back during initialization (btw very questionable design choice), and at that stage the driver doesn't know yet which device type it is going to drive. So the answer is: 1. Can't have two structures. 2. Same behaviour across all netdev devices. > > Sorry, at the very least you need better explanation for this. Was it better explained now?
