OK, I will follow up. after add FLAG_NOARP, how should I handle
IFF_NOARP? will I do it in cdc_ncm.c or usb_net.c?

yes. usbnet has FLAG_POINTTOPOINT, but that's nothing to do with
IFF_POINTTOPOINT. At least we should do something to handle
relationship of these flags rather than only have different names.
or new flag FLAG_NOARP could be introduced to corresponding to IFF_NOARP.

It's rather about the network than any given devices, right?
