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.
# All the following symbols are dependent on NETDEVICES - do not repeat
# that for each of the symbols.
if NETDEVICES
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.
source "drivers/net/arcnet/Kconfig"
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.
if NET_ETHERNET
config NET_PCI
bool "EISA, VLB, PCI and on board controllers"
depends on ISA || EISA || PCI
help
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.

The corresponding Linux backend driver is enabled by the
CONFIG_XEN_NETDEV_BACKEND option.
If you are compiling a kernel for use as Xen guest, you
should say Y here. To compile this driver as a module, chose
M here: the module will be called xen-netfront.
config XEN_NETDEV_BACKEND
tristate "Xen backend network device"
depends on XEN_BACKEND
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
domain (often this is domain 0) you should say Y here. To
compile this driver as a module, chose M here: the module
will be called xen-netback.
config RIONET

config FDDI
tristate "FDDI driver support"
depends on (PCI || EISA || TC)
help
Fiber Distributed Data Interface is a high speed local area network
design; essentially a replacement for high speed Ethernet. FDDI can
run over copper or fiber. If you are connected to such a network and
want a driver for the FDDI card in your computer, say Y here (and
then also Y to the driver for your FDDI card, below). Most people
will say N.
config DEFXX
tristate "Digital DEFTA/DEFEA/DEFPA adapter support"
depends on FDDI && (PCI || EISA || TC)
---help---
This is support for the DIGITAL series of TURBOchannel (DEFTA),
EISA (DEFEA) and PCI (DEFPA) controllers which can connect you
to a local FDDI network.
To compile this driver as a module, choose M here: the module
will be called defxx. If unsure, say N.
config DEFXX_MMIO
bool
prompt "Use MMIO instead of PIO" if PCI || EISA
depends on DEFXX
default n if PCI || EISA
default y
---help---
This instructs the driver to use EISA or PCI memory-mapped I/O
(MMIO) as appropriate instead of programmed I/O ports (PIO).
Enabling this gives an improvement in processing time in parts
of the driver, but it may cause problems with EISA (DEFEA)
adapters. TURBOchannel does not have the concept of I
