The main problem is that these devices don't support ethernet. They
support IP (v4 and _maybe_ v6) with an ethernet header. Many of them
will do ARP (and IPv6 ND) as well to complete the picture, but some of
them don't and

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?

IFF_NOARP is already done for other WWAN devices (sierra_net, hso,
cdc-ether, cdc-phonet, lg-vl600, etc) so there is some precedent. Some
drivers (phonet, hso) set *both* POINTTOPOINT and NOARP. Is that
redundant,
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.

I can't answer any of your questions unless you tell me what the
real limitation of these devices is.
It's rather about the network than any given devices, right?
