[PATCH] cdc_ether: flag the Cinterion PLS8 modem by gemalto as WWAN

[Bassem Boubaker]

    The Cinterion PL8 is an LTE modem with 2 possible WWAN interfaces.

    The modem is  controlled via AT commands through the exposed TTYs.

    AT^SWWAN write command can be used to activate or deactivate a WWAN
    connection for a PDP context defined with AT+CGDCONT. UE supports
    two WWAN adapter. Both WWAN adapters can be activated a the same time

This is defined as CINTERION_VENDOR_ID in drivers/usb/serial/option.c.

I have no idea which defintion is most correct, but I believe the macros
should be kept identical whatever you decide. Anything else is just
unnecessarily confusing.

IMHO the company name tracking macros have grown beyond useful a long
time ago. They just make it harder to grep for the IDs without adding
any useful information whatsoever. And because you have cases like this
where the same number end up having different names, they sometimes hide
information which a plain number would have revealed.

Hi,

I concur. Could you redo the patch and just use a plain number?
