sjur.brandeland@stericsson.com 7ad65bf68d caif: Add support for CAIF over CDC NCM USB interface
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.

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.
config CAIF_DEBUG
bool "Enable Debug"
depends on CAIF
default n
--- help ---
Enable the inclusion of debug code in the CAIF stack.
Be aware that doing this will impact performance.
If unsure say N.
config CAIF_NETDEV
tristate "CAIF GPRS Network device"
depends on CAIF
default CAIF
---help---
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.
config CAIF_USB
tristate "CAIF USB support"
depends on CAIF
default n
---help---
Say Y if you are using CAIF over USB CDC NCM.
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 N.
