- ---help---
- This driver supports several kinds of network links over USB,
- with "minidrivers" built around a common network driver core
- that supports deep queues for efficient transfers. (This gives
- better performance with small packets and at high speeds).
-
- The USB host runs "usbnet", and the other end of the link might be:
-
- - Another USB host, when using USB "network" or "data transfer"
- cables. These are often used to network laptops to PCs, like
- "Laplink" parallel cables or some motherboards. These rely
- on specialized chips from many suppliers.
-
- - An intelligent USB gadget, perhaps embedding a Linux system.
- These include PDAs running Linux (iPaq, Yopy, Zaurus, and
- others), and devices that interoperate using the standard
- CDC-Ethernet specification (including many cable modems).
-
- - Network adapter hardware (like those for 10/100 Ethernet) which
- uses this driver framework.
-
- The link will appear with a name like "usb0", when the link is
- a two-node link, or "eth0" for most CDC-Ethernet devices. Those
- two-node links are most easily managed with Ethernet Bridging
- (CONFIG_BRIDGE) instead of routing.
-
- For more information see <http://www.linux-usb.org/usbnet/>.
-
- To compile this driver as a module, choose M here: the
- module will be called usbnet.

- help
- This option adds support for ASIX AX88xxx based USB 2.0
- 10/100 Ethernet adapters.
-
- This driver should work with at least the following devices:
- * Aten UC210T
- * ASIX AX88172
- * Billionton Systems, USB2AR
- * Buffalo LUA-U2-KTX
- * Corega FEther USB2-TX

- * Netgear FA120
- * Sitecom LN-029
- * Intellinet USB 2.0 Ethernet
- * ST Lab USB 2.0 Ethernet
- * TrendNet TU2-ET100
-
- This driver creates an interface named "ethX", where X depends on
- what other networking devices you have in use.
-
-
-config USB_NET_CDCETHER
- tristate "CDC Ethernet support (smart devices such as cable modems)"
- depends on USB_USBNET
- default y
- help
- This option supports devices conforming to the Communication Device
- Class (CDC) Ethernet Control Model, a specification that's easy to
- implement in device firmware. The CDC specifications are available
- from <http://www.usb.org/>.
-
- CDC Ethernet is an implementation option for DOCSIS cable modems
- that support USB connectivity, used for non-Microsoft USB hosts.
- The Linux-USB CDC Ethernet Gadget driver is an open implementation.
- This driver should work with at least the following devices:
-
- * Ericsson PipeRider (all variants)
- * Motorola (DM100 and SB4100)
- * Broadcom Cable Modem (reference design)
- * Toshiba PCX1100U
- * ...
-
- This driver creates an interface named "ethX", where X depends on
- what other networking devices you have in use. However, if the
- IEEE 802 "local assignment" bit is set in the address, a "usbX"
- name is used instead.

-
-config USB_NET_RNDIS_HOST
- tristate "Host for RNDIS and ActiveSync devices (EXPERIMENTAL)"
- depends on USB_USBNET && EXPERIMENTAL
- select USB_NET_CDCETHER
- help
- This option enables hosting "Remote NDIS" USB networking links,
- as encouraged by Microsoft (instead of CDC Ethernet!) for use in
- various devices that may only support this protocol. A variant
- of this protocol (with even less public documentation) seems to
- be at the root of Microsoft's "ActiveSync" too.
-
- Avoid using this protocol unless you have no better options.
- The protocol specification is incomplete, and is controlled by
- (and for) Microsoft; it isn't an "Open" ecosystem or market.
-
-config USB_NET_CDC_SUBSET
- tristate "Simple USB Network Links (CDC Ethernet subset)"
- depends on USB_USBNET
- default y
- help
- This driver module supports USB network devices that can work
- without any device-specific information. Select it if you have
- one of these drivers.
-
- Note that while many USB host-to-host cables can work in this mode,
- that may mean not being able to talk to Win32 systems or more
- commonly not being able to handle certain events (like replugging
- the host on the other end) very well. Also, these devices will
- not generally have permanently assigned Ethernet addresses.
-
-config USB_ALI_M5632
- boolean "ALi M5632 based 'USB 2.0 Data Link' cables"

- depends on USB_NET_CDC_SUBSET
- help
- Choose this option if you're using a host-to-host cable
- based on this design. Note that AnchorChips is now a
- Cypress brand.
-
-config USB_BELKIN
- boolean "eTEK based host-to-host cables (Advance, Belkin, ...)"
- depends on USB_NET_CDC_SUBSET
- default y
- help
- Choose this option if you're using a host-to-host cable
- based on this design: two NetChip 2890 chips and an Atmel
- microcontroller, with LEDs that indicate traffic.
-
-config USB_ARMLINUX
- boolean "Embedded ARM Linux links (iPaq, ...)"
- depends on USB_NET_CDC_SUBSET
- default y
- help
- Choose this option to support the "usb-eth" networking driver
- used by most of the ARM Linux community with device controllers
- such as the SA-11x0 and PXA-25x UDCs, or the tftp capabilities
- in some PXA versions of the "blob" boot loader.
-
- Linux-based "Gumstix" PXA-25x based systems use this protocol
- to talk with other Linux systems.
-
- Although the ROMs shipped with Sharp Zaurus products use a
- different link level framing protocol, you can have them use
- this simpler protocol by installing a different kernel.
-
-config USB_EPSON2888
- boolean "Epson 2888 based firmware (DEVELOPMENT)"
- depends on USB_NET_CDC_SUBSET
- help
- Choose this option to support the usb networking links used
- by some sample firmware from Epson.
-
-config USB_KC2190
- boolean "KT Technology KC2190 based cables (InstaNet)"
- depends on USB_NET_CDC_SUBSET && EXPERIMENTAL
- help
-  Choose this option if you're using a host-to-host cable
-  with one of these chips.
-
-config USB_NET_ZAURUS
- tristate "Sharp Zaurus (stock ROMs) and compatible"
- depends on USB_USBNET
- select USB_NET_CDCETHER
- select CRC32
- default y
- help
- Choose this option to support the usb networking links used by
- Zaurus models like the SL-5000D, SL-5500, SL-5600, A-300, B-500.
- This also supports some related device firmware, as used in some
- PDAs from Olympus and some cell phones from Motorola.
-
- If you install an alternate image, such as the Linux 2.6 based
- versions of OpenZaurus, you should no longer need to support this
- protocol. Only the "eth-fd" or "net_fd" drivers in these devices
- really need this non-conformant variant of CDC Ethernet (or in
- some cases CDC MDLM) protocol, not "g_ether".

-/*
- * This supports simple USB network links that don't require any special
- * framing or hardware control operations. The protocol used here is a
- * strict subset of CDC Ethernet, with three basic differences reflecting
- * the goal that almost any hardware should run it:
- *
- * - Minimal runtime control: one interface, no altsettings, and
- * no vendor or class specific control requests. If a device is
- * configured, it is allowed to exchange packets with the host.
- * Fancier models would mean not working on some hardware.
- *
- * - Minimal manufacturing control: no IEEE "Organizationally
- * Unique ID" required, or an EEPROMs to store one. Each host uses
- * one random "locally assigned" Ethernet address instead, which can
- * of course be overridden using standard tools like "ifconfig".
- * (With 2^46 such addresses, same-net collisions are quite rare.)
- *
- * - There is no additional framing data for USB. Packets are written
- * exactly as in CDC Ethernet, starting with an Ethernet header and
- * terminated by a short packet. However, the host will never send a
- * zero length packet; some systems can't handle those robustly.
- *
- * Anything that can transmit and receive USB bulk packets can implement
- * this protocol. That includes both smart peripherals and quite a lot
- * of "host-to-host" USB cables (which embed two devices back-to-back).
- *
- * Note that although Linux may use many of those host-to-host links
- * with this "cdc_subset" framing, that doesn't mean there may not be a
- * better approach. Handling the "other end unplugs/replugs" scenario
- * well tends to require chip-specific vendor requests. Also, Windows
- * peers at the other end of host-to-host cables may expect their own
- * framing to be used rather than this "cdc_subset" model.

- * ChangeLog:
- * .... Most of the time spent on reading sources & docs.
- * v0.2.x First official release for the Linux kernel.
- * v0.3.0 Beutified and structured, some bugs fixed.
- * v0.3.x URBifying bulk requests and bugfixing. First relatively
- * stable release. Still can touch device's registers only
- * from top-halves.
- * v0.4.0 Control messages remained unurbified are now URBs.
- * Now we can touch the HW at any time.
- * v0.4.9 Control urbs again use process context to wait. Argh...
- * Some long standing bugs (enable_net_traffic) fixed.
- * Also nasty trick about resubmiting control urb from
- * interrupt context used. Please let me know how it
- * behaves. Pegasus II support added since this version.
- * TODO: suppressing HCD warnings spewage on disconnect.
- * v0.4.13 Ethernet address is now set at probe(), not at open()
- * time as this seems to break dhcpd.
- * v0.5.0 branch to 2.5.x kernels
- * v0.5.1 ethtool support added
- * v0.5.5 rx socket buffers are in a pool and the their allocation
- * is out of the interrupt routine.

- * - In some cases, MS-Windows will emit undocumented requests; this
- * matters more to peripheral implementations than host ones.
- *
- * Moreover there's a no-open-specs variant of RNDIS called "ActiveSync".
- *
- * For these reasons and others, ** USE OF RNDIS IS STRONGLY DISCOURAGED ** in

- * - Framing appends a CRC, which the spec says drivers "must not" do;
- * - Transfers data in altsetting zero, instead of altsetting 1;
