Need to understand your specific concern. Do you oppose introducing new API to support ethtool ops and net_device_ops? 
Or your concern is on the implementation. If that's latter. 
Do you oppose adding a new library to implement ethtool ops and net_device_ops?
    If so, are you satisfied with my previous answer on avoiding polluting ethdev APIs? 
        If not, do you suggest integrating ethtool APIs into ethdev API?
    If not, is your concern on the implementation of common functionality between ethtool and ethdev APIs?
        If so, as explained, it is designed to provide a unified interface to assist users to migrate from kernel ethtool/net-device-op API to DPDK
BTW, as my reply to Steve's comment, more ops are on their way. This patch is to open up the interface.
