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.

The "Communication CPU to Application CPU Interface" (CAIF) is a packet
|
|
based connection-oriented MUX protocol developed by ST-Ericsson for use
|
|
with its modems. It is accessed from user space as sockets (PF_CAIF).
|
|
|
|
Say Y (or M) here if you build for a phone product (e.g. Android or
|
|
MeeGo ) that uses CAIF as transport, if unsure say N.
|
|
|
|
If you select to build it as module then CAIF_NETDEV also needs to be
|
|
built as modules. You will also need to say yes to any CAIF physical
|
|
devices that your platform requires.
|
|
|
|
See Documentation/networking/caif for a further explanation on how to
|
|
use and configure CAIF.

Enable the inclusion of debug code in the CAIF stack.

Be aware that doing this will impact performance.

Say Y if you will be using a CAIF based GPRS network device.
|
|
This can be either built-in or a loadable module,
|
|
If you select to build it as a built-in then the main CAIF device must
|
|
also be a built-in.
|

If unsure say Y.
