    caif: Add support for CAIF over CDC NCM USB interface · 7ad65bf6
    sjur.brandeland@stericsson.com authored
    NCM 1.0 does not support anything but Ethernet framing, hence
    CAIF payload will be put into Ethernet frames.
    Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson),
    product-id 0x230f (NCM). In this variant only CAIF payload is sent over
    the NCM interface.
    The CAIF stack (cfusbl.c) will when USB interface register first check if
    we got a CDC NCM USB interface with the right VID, PID.
    It will then read the device's Ethernet address and create a 'template'
    Ethernet TX header, using a broadcast address as the destination address,
    and EthType 0x88b5 (802.1 Local Experimental - vendor specific).
    A protocol handler for 0x88b5 is setup for reception of CAIF frames from
    the CDC NCM USB interface.
