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"

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.

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

---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
tristate "Virtual ethernet pair device"

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.

---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

help
This driver allows the kernel to act as a Xen network driver
domain which exports paravirtual network devices to other
Xen domains. These devices can be accessed by any operating
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
etc in order to provide full network connectivity.
If you are compiling a kernel to run in a Xen network driver
