	  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.

	  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

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.

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>.

	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 IFB

	  This is an intermediate driver that allows sharing of

	  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.

	  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"
	depends on MACVLAN
	depends on INET
	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.

	  This allows one to create vxlan virtual interfaces that provide
	  Layer 2 Networks over Layer 3 Networks. VXLAN is often used
	  to tunnel virtual network infrastructure in virtualized environments.
	  For more information see:
	    http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02

	  To compile this driver as a module, choose M here: the module

config TUN

	---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

	  This is the virtual network driver for virtio.  It can be used with
	  lguest or QEMU based VMMs (like KVM or Xen).  Say Y or M.

config NLMON
	tristate "Virtual netlink monitoring device"
	---help---
	  This option enables a monitoring net device for netlink skbs. The
	  purpose of this is to analyze netlink messages with packet sockets.
	  Thus applications like tcpdump will be able to see local netlink
	  messages if they tap into the netlink device, record pcaps for further
	  diagnostics, etc. This is mostly intended for developers or support
	  to debug netlink issues. If unsure, say N.

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