It is. However the current way is driver-specific, not correct. For mlx5, we need the same, it cannot be done in this way. Do devlink is the correct way to go. >Why not hide echo/cat in iproute2 instead of adding parallel netlink api? >Or this is for switches instead of nics? >Then why it's not adding to switchdev? Note this is not specific to switch ASICs. This is for all network devices.
