 	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 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 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 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 NET_FC
 	bool "Fibre Channel driver support"
 	depends on SCSI && PCI
 	help
 	  Fibre Channel is a high speed serial protocol mainly used to connect
 	  large storage devices to the computer; it is compatible with and
 	  intended to replace SCSI.

 	  If you intend to use Fibre Channel, you need to have a Fibre channel
 	  adaptor card in your computer; say Y here and to the driver for your
 	  adaptor below. You also should have said Y to "SCSI support" and
 	  "SCSI generic support".

 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.

 config IFB

 	---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 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 NETCONSOLE

 config NETCONSOLE_DYNAMIC

 	  at runtime through a userspace interface exported using configfs.
 	  See <file:Documentation/networking/netconsole.txt> for details.

 config TUN
 	tristate "Universal TUN/TAP device driver support"

 	---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 VIRTIO_NET

 	  This is a driver for the General Instrument (also known as

 	  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

 	  system that implements a compatible front end.

 	  The corresponding Linux frontend driver is enabled by the

 	  The backend driver presents a standard network device
 	  endpoint for each paravirtual network device to the driver

 	  etc in order to provide full network connectivity.

 	  If you are compiling a kernel to run in a Xen network driver
