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. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.
