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 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. It won't
	  enlarge your kernel. 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>.

	  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 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 MACVLAN
	tristate "MAC-VLAN support"
	---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"
	depends on MACVLAN
	depends on INET
	select TAP
	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
	  macvtap', 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.

    depends on INET
    depends on IPV6 || !IPV6
    depends on NETFILTER
    select NET_L3_MASTER_DEV
    ---help---
      This allows one to create virtual devices off of a main interface
      and packets will be delivered based on the dest L3 (IPv6/IPv4 addr)
      on packets. All interfaces (including the main interface) share L2
      making it transparent to the connected L2 switch.

      Ipvlan devices can be added using the "ip" command from the
      iproute2 package starting with the iproute2-3.19 release:

      "ip link add link <main-dev> [ NAME ] type ipvlan"

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

config GTP
	tristate "GPRS Tunneling Protocol datapath (GTP-U)"
	depends on INET && NET_UDP_TUNNEL
	select NET_IP_TUNNEL
	---help---
	  This allows one to create gtp virtual interfaces that provide
	  the GPRS Tunneling Protocol datapath (GTP-U). This tunneling protocol
	  is used to prevent subscribers from accessing mobile carrier core
	  network infrastructure. This driver requires a userspace software that
	  implements the signaling protocol (GTP-C) to update its PDP context
	  base, such as OpenGGSN <http://git.osmocom.org/openggsn/). This
	  tunneling protocol is implemented according to the GSM TS 09.60 and
	  3GPP TS 29.060 standards.

	  To compile this drivers as a module, choose M here: the module
	  wil be called gtp.

config TUN
	tristate "Universal TUN/TAP device driver support"
	depends on INET
	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 TAP
	tristate
	---help---
	  This option is selected by any driver implementing tap user space
	  interface for a virtual interface to re-use core tap functionality.

config TUN_VNET_CROSS_LE
	bool "Support for cross-endian vnet headers on little-endian kernels"
	default n
	---help---
	  This option allows TUN/TAP and MACVTAP device drivers in a
	  little-endian kernel to parse vnet headers that come from a
	  big-endian legacy virtio device.

	  Userspace programs can control the feature using the TUNSETVNETBE
	  and TUNGETVNETBE ioctls.

	  Unless you have a little-endian system hosting a big-endian virtual
	  machine with a legacy virtio NIC, you should say N.

config VETH

	  This is the virtual network driver for virtio.  It can be used with
	  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.

config NET_VRF
