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

Changes:
include/linux/usb/usbnet.h:
- a new flag to indicate driver's capability to accumulate IP packets in Tx
direction and extract several packets from single skb in Rx direction.
drivers/net/usb/usbnet.c:
- the procedure of counting packets in usbnet was updated due to the
accumulating of IP packets in the driver
- no short packets are sent if indicated by the flag in driver_info
structure

The smsc95xx driver currently generates a new random MAC address
every time the interface is brought up. This makes it impossible to
override using the standard `ifconfig hw ether` approach.
Past patches tried to make the MAC address a module parameter or
base it off the die ID, but it seems to me much simpler (and
hopefully less controversial) to stick with the current random
generation scheme, but allow the user to change the address.
This patch does exactly that - it moves the random address
generation from smsc95xx_reset() into smsc95xx_bind(), so that it is
done once on module load, not on every ifup. The user can then
override this using the standard mechanisms.
Applies against 2.6.35 and linux-2.6 head.

The 'wwan' devtype is meant for devices that require preconfiguration
and *every* time setup before the ethernet interface can be used, like
cellular modems which require a series of setup commands on serial ports
or other mechanisms before the ethernet interface will handle packets.
As ipheth only requires one-per-hotplug pairing setup with no
preconfiguration (like APN, phone #, etc) and the network interface is
usable at any time after that initial setup, remove the incorrect
devtype wwan.

This patch introduces cx82310_eth driver - driver for USB ethernet port of
ADSL routers based on Conexant CX82310 chips. Such routers usually have
ethernet port(s) too which are bridged together with the USB ethernet port,
allowing the USB-connected machine to communicate to the network (and also
internet through the ADSL, of course).
This is my first driver, so please check thoroughly. As there's no protocol
documentation, it was done with usbsnoop dumps from Windows driver, some
parts (the commands) inspired by cxacru driver and also other usbnet drivers.
The driver passed my testing - some real work and also pings sized from 0 to
65507 B.
The only problem I found is the ifconfig error counter. When I return 0 (or 1
but empty skb) from rx_fixup(), usbnet increases the error counter although
it's not an error condition (because packets can cross URB boundaries). Maybe
the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some
other value, e.g. 2)?
The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems
using cxacru driver (they probably use the same chipset but simpler
firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB
MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The
driver matches only devices with class 255 and checks for the iProduct string
during init. I already posted a patch for the cxacru driver to ignore these
devices.

The driver name and bus address for a net_device can normally be found
through the driver model now. Instead of requiring drivers to provide
this information redundantly through the ethtool_ops::get_drvinfo
operation, use the driver model to do so if the driver does not define
the operation. Since ETHTOOL_GDRVINFO no longer requires the driver
to implement any operations, do not require net_device::ethtool_ops to
be set either.
Remove implementations of get_drvinfo and ethtool_ops that provide
only this information.

This patch makes rx_submit() return an error code, and makes some call sites
that care check the return value. This is important because it lets us properly
handle cases where the device isn't ready to handle URB submissions (e.g., when
it is autosuspended under some drivers); previously, we would attempt and fail
to submit URBs and reschedule ourselves to try and fail again. This patch is
against Linus's 2.6 repo commit 45d7f32c7a.
