menuconfig NETDEVICES
	default y if UML
	depends on NET
	bool "Network device support"
	---help---
	  You can say N here if you don't intend to connect your Linux box to
	  any other computer at all.

	  You'll have to say Y if your computer contains a network card that
	  you want to use under Linux. If you are going to run SLIP or PPP over
	  telephone line or null modem cable you need say Y here. Connecting
	  two machines with parallel ports using PLIP needs this, as well as
	  AX.25/KISS for sending Internet traffic over amateur radio links.

	  See also "The Linux Network Administrator's Guide" by Olaf Kirch and
	  Terry Dawson. Available at <http://www.tldp.org/guides.html>.

	  If unsure, say Y.

config IFB
	tristate "Intermediate Functional Block support"
	depends on NET_CLS_ACT
	---help---
	  This is an intermediate driver that allows sharing of
	  resources.
	  To compile this driver as a module, choose M here: the module
	  will be called ifb.  If you want to use more than one ifb
	  device at a time, you need to compile this driver as a module.
	  Instead of 'ifb', the devices will then be called 'ifb0',
	  'ifb1' etc.
	  Look at the iproute2 documentation directory for usage etc

config DUMMY
	tristate "Dummy net driver support"
	---help---
	  This is essentially a bit-bucket device (i.e. traffic you send to
	  this device is consigned into oblivion) with a configurable IP
	  address. It is most commonly used in order to make your currently
	  inactive SLIP address seem like a real address for local programs.
	  If you use SLIP or PPP, you might want to say Y here. Since this
	  thing often comes in handy, the default is Y. It won't enlarge your
	  kernel either. What a deal. Read about it in the Network
	  Administrator's Guide, available from
	  <http://www.tldp.org/docs.html#guide>.

	  To compile this driver as a module, choose M here: the module
	  will be called dummy.  If you want to use more than one dummy
	  device at a time, you need to compile this driver as a module.
	  Instead of 'dummy', the devices will then be called 'dummy0',
	  'dummy1' etc.

config BONDING
	tristate "Bonding driver support"
	depends on INET
	depends on IPV6 || IPV6=n
	---help---
	  Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
	  Channels together. This is called 'Etherchannel' by Cisco,
	  'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.

	  The driver supports multiple bonding modes to allow for both high
	  performance and high availability operation.

	  Refer to <file:Documentation/networking/bonding.txt> for more
	  information.

	  To compile this driver as a module, choose M here: the module
	  will be called bonding.

config MACVLAN
	tristate "MAC-VLAN support (EXPERIMENTAL)"
	depends on EXPERIMENTAL
	---help---
	  This allows one to create virtual interfaces that map packets to
	  or from specific MAC addresses to a particular interface.

	  Macvlan devices can be added using the "ip" command from the
	  iproute2 package starting with the iproute2-2.6.23 release:

	  "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"

	  To compile this driver as a module, choose M here: the module
	  will be called macvlan.

config MACVTAP
	tristate "MAC-VLAN based tap driver (EXPERIMENTAL)"
	depends on MACVLAN
	help
	  This adds a specialized tap character device driver that is based
	  on the MAC-VLAN network interface, called macvtap. A macvtap device
	  can be added in the same way as a macvlan device, using 'type
	  macvlan', and then be accessed through the tap user space interface.

	  To compile this driver as a module, choose M here: the module
	  will be called macvtap.

config EQUALIZER
	tristate "EQL (serial line load balancing) support"
	---help---
	  If you have two serial connections to some other computer (this
	  usually requires two modems and two telephone lines) and you use
	  SLIP (the protocol for sending Internet traffic over telephone
	  lines) or PPP (a better SLIP) on them, you can make them behave like
	  one double speed connection using this driver.  Naturally, this has
	  to be supported at the other end as well, either with a similar EQL
	  Linux driver or with a Livingston Portmaster 2e.

	  Say Y if you want this and read
	  <file:Documentation/networking/eql.txt>.  You may also want to read
	  section 6.2 of the NET-3-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  To compile this driver as a module, choose M here: the module
	  will be called eql.  If unsure, say N.

config TUN
	tristate "Universal TUN/TAP device driver support"
	select CRC32
	---help---
	  TUN/TAP provides packet reception and transmission for user space
	  programs.  It can be viewed as a simple Point-to-Point or Ethernet
	  device, which instead of receiving packets from a physical media,
	  receives them from user space program and instead of sending packets
	  via physical media writes them to the user space program.

	  When a program opens /dev/net/tun, driver creates and registers
	  corresponding net device tunX or tapX.  After a program closed above
	  devices, driver will automatically delete tunXX or tapXX device and
	  all routes corresponding to it.

	  Please read <file:Documentation/networking/tuntap.txt> for more
	  information.

	  To compile this driver as a module, choose M here: the module
	  will be called tun.

	  If you don't know what to use this for, you don't need it.

config VETH
	tristate "Virtual ethernet pair device"
	---help---
	  This device is a local ethernet tunnel. Devices are created in pairs.
	  When one end receives the packet it appears on its pair and vice
	  versa.

config NET_SB1000
	tristate "General Instruments Surfboard 1000"
	depends on PNP
	---help---
	  This is a driver for the General Instrument (also known as
	  NextLevel) SURFboard 1000 internal
	  cable modem. This is an ISA card which is used by a number of cable
	  TV companies to provide cable modem access. It's a one-way
	  downstream-only cable modem, meaning that your upstream net link is
	  provided by your regular phone modem.

	  At present this driver only compiles as a module, so say M here if
	  you have this card. The module will be called sb1000. Then read
	  <file:Documentation/networking/README.sb1000> for information on how
	  to use this module, as it needs special ppp scripts for establishing
	  a connection. Further documentation and the necessary scripts can be
	  found at:

	  <http://www.jacksonville.net/~fventuri/>
	  <http://home.adelphia.net/~siglercm/sb1000.html>
	  <http://linuxpower.cx/~cable/>

	  If you don't have this card, of course say N.

config MII
	tristate "Generic Media Independent Interface device support"
	help
	  Most ethernet controllers have MII transceiver either as an external
	  or internal device.  It is safe to say Y or M here even if your
	  ethernet card lacks MII.

menuconfig NET_ETHERNET
	bool "Ethernet (10 or 100Mbit)"
	depends on !UML
	---help---
	  Ethernet (also called IEEE 802.3 or ISO 8802-2) is the most common
	  type of Local Area Network (LAN) in universities and companies.

	  Common varieties of Ethernet are: 10BASE-2 or Thinnet (10 Mbps over
	  coaxial cable, linking computers in a chain), 10BASE-T or twisted
	  pair (10 Mbps over twisted pair cable, linking computers to central
	  hubs), 10BASE-F (10 Mbps over optical fiber links, using hubs),
	  100BASE-TX (100 Mbps over two twisted pair cables, using hubs),
	  100BASE-T4 (100 Mbps over 4 standard voice-grade twisted pair
	  cables, using hubs), 100BASE-FX (100 Mbps over optical fiber links)
	  [the 100BASE varieties are also known as Fast Ethernet], and Gigabit
	  Ethernet (1 Gbps over optical fiber or short copper links).

	  If your Linux machine will be connected to an Ethernet and you have
	  an Ethernet network interface card (NIC) installed in your computer,
	  say Y here and read the Ethernet-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>. You will then also have
	  to say Y to the driver for your particular NIC.

	  Note that the answer to this question won't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about Ethernet network cards. If unsure, say N.

config NET_PCI
	bool "EISA, VLB, PCI and on board controllers"
	depends on ISA || EISA || PCI

	  This is another class of network cards which attach directly to the
	  bus. If you have one of those, say Y and read the Ethernet-HOWTO,
	  available from <http://www.tldp.org/docs.html#howto>.

	  Note that the answer to this question doesn't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about this class of network cards. If you say Y, you
	  will be asked for your specific card in the following questions. If
	  you are unsure, say Y.

config NET_POCKET
	bool "Pocket and portable adapters"
	depends on PARPORT
	---help---
	  Cute little network (Ethernet) devices which attach to the parallel
	  port ("pocket adapters"), commonly used with laptops. If you have
	  one of those, say Y and read the Ethernet-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  If you want to plug a network (or some other) card into the PCMCIA
	  (or PC-card) slot of your laptop instead (PCMCIA is the standard for
	  credit card size extension cards used by all modern laptops), you
	  need the pcmcia-cs package (location contained in the file
	  <file:Documentation/Changes>) and you can say N here.

	  Laptop users should read the Linux Laptop home page at
	  <http://www.linux-on-laptops.com/> or
	  Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>.

	  Note that the answer to this question doesn't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about this class of network devices. If you say Y, you
	  will be asked for your specific device in the following questions.

	  system that implements a compatible front end.

	  The corresponding Linux frontend driver is enabled by the
	  CONFIG_XEN_NETDEV_FRONTEND configuration option.

	  The backend driver presents a standard network device
	  endpoint for each paravirtual network device to the driver
	  domain network stack. These can then be bridged or routed
