The patch provides USB CDC NCM host driver support in the Linux Kernel.

Changes:
drivers/net/usb/cdc_ncm.c:
- initial submission of the CDC NCM host driver;
- verified on Intel 32/64 bit, Intel Atom, ST-Ericsson U8500 (ARM)
- throughput measured over 100 Mbits duplex;
- driver supports 16-bit NTB format only, but it is more than enough for
  transfers up to 64K;
- driver can handle up to 32 datagrams in received NTB;
- timer is used to collect several packets in Tx direction

drivers/net/usb/Kconfig:
- a new entry to compile CDC NCM host driver

	  This driver provides support for CDC NCM (Network Control Model

	  Device USB Class Specification). The CDC NCM specification is

	  available from <http://www.usb.org/>.



	  Say "y" to link the driver statically, or "m" to build a

	  dynamically linked module.



	  This driver should work with at least the following devices:

	    * ST-Ericsson M700 LTE FDD/TDD Mobile Broadband Modem (ref. design)

	    * ST-Ericsson M5730 HSPA+ Mobile Broadband Modem (reference design)
