HUWAEI E1750 NDISDUP


Is the difference between the two modes just the usb_modeswitch
commands?  I see they have different USB IDs between first and second
runs.

In any case, if ModemManager can handle the device, we would expect
NetworkManager to handle it as well.  In general, we'd prefer to handle
the device with QMI and the QMI network commands instead of NDISDUP,
unless the device doesn't implement the QMI stack very well.

In both cases, however, ModemManager should be doing the right thing
wtih either QMI or NDISDUP, then advertise that the IP configuration
method should be "DHCP", and NetworkManager will perform DHCP on the
interface and set up the IP configuration.

usb_wwan -
          \
           - option



This and similar devices are apparently working in this way also.
Is it planned to support such a mode in the NetworkManager?
