    Subject[PATCH AUTOSEL 6.1 17/53] net: usb: cdc_ether: add support for Thales Cinterion PLS62-W modem
    Date
    From: Hui Wang <hui.wang@canonical.com>

    [ Upstream commit eea8ce81fbb544e3caad1a1c876ba1af467b3d3c ]

    This modem has 7 interfaces, 5 of them are serial interfaces and are
    driven by cdc_acm, while 2 of them are wwan interfaces and are driven
    by cdc_ether:
    If 0: Abstract (modem)
    If 1: Abstract (modem)
    If 2: Abstract (modem)
    If 3: Abstract (modem)
    If 4: Abstract (modem)
    If 5: Ethernet Networking
    If 6: Ethernet Networking

    Without this change, the 2 network interfaces will be named to usb0
    and usb1, our QA think the names are confusing and filed a bug on it.

    After applying this change, the name will be wwan0 and wwan1, and
    they could work well with modem manager.
