Yes, that's the right way to go. Currently, the kernel does not provide a generic framework for that and I am not aware of any projects in order to define it. Could it be something to discuss on netdev@? So, as a workaround, some proprietary solutions get implemented in order to get ethtool running with any DPDK PMD. Best regards, Vincent
