Introducing driver for the network port of Samsung Kalmia based USB LTE modems.
It has also an ACM interface that previous patches associates with the "option"
module. To access those interfaces, the modem must first be switched from modem
mode using a tool like usb_modeswitch.
As the proprietary protocol has been discovered by watching the MS Windows driver
behavior, there might be errors in the protocol handling, but stable and fast
connection has been established for hours with Norwegian operator NetCom that
distributes this modem with their LTE/4G subscription.
More and updated information about how to use this driver is available here:

This adds a driver for the CDC Ethernet part of this modem. The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data. The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored. All information is based on a usb traffic log from a
Windows machine.
On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
Userspace scripts are required to talk to the CDC ACM port.

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

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.

Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().
The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).
This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.
This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.
Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

Add new driver to use tethering with an iPhone device. After initial submission,
apply fixes to fit the new driver into the kernel standards.
There are still a couple of minor (almost cosmetic-level) issues, but the driver
is fully functional right now.

This patch adds a driver for SMSC's LAN7500 family of USB 2.0
to gigabit ethernet adapters. It's loosely based on the smsc95xx
driver but the device registers for LAN7500 are completely different.

Many Nokia handsets support a Phonet interface to the cellular modem
via a vendor-specific USB interface. CDC Phonet follows the
Communications Device Class model, with one control interface, and
and a pair of inactive and active data alternative interface. The later
has two bulk endpoint, one per direction.
This was tested against Nokia E61, Nokia N95, and the existing Phonet
gadget function for the Linux composite USB gadget framework.

This introduces a CDC Ethernet Emulation Model (EEM) host side
driver to support USB EEM devices.
EEM is different from the Ethernet Control Model (ECM) currently
supported by the "CDC Ethernet" driver. One key difference is
that it doesn't require of USB interface alternate settings to
manage interface state; some maldesigned hardware can't handle
that part of USB. It also avoids a separate USB interface for
control and status updates.

It is preferable to group drivers by usage (net, scsi, ATA, ...) than
by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer
is probably less qualified on networking issues than a networking
maintainer. Also, from a practical standpoint, chips often
appear on multiple buses, which is why we do not put drivers into
drivers/pci/net.
