 * Network device configuration

Network device support

 * Option: NETDEVICES
 * Kernel Versions: 2.6.15.6 ...
 * depends on NET
 * (on/off) Network device support
 * 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 .
 * If unsure, say Y.


 * All the following symbols are dependent on NETDEVICES - do not repeat
 * that for each of the symbols.

NETDEVICES


 * Option: DUMMY
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Dummy net driver support
 * 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 .
 * 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.


 * Option: BONDING
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Bonding driver support
 * depends on INET
 * 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  for more information.
 * To compile this driver as a module, choose M here: the module will be called bonding.


 * Option: EQUALIZER
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) EQL (serial line load balancing) support
 * 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 . You may also want to read section 6.2 of the NET-3-HOWTO, available from .
 * To compile this driver as a module, choose M here: the module will be called eql. If unsure, say N.


 * Option: TUN
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Universal TUN/TAP device driver support
 * select CRC32
 * 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  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.


 * Option: NET_SB1000
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) General Instruments Surfboard 1000
 * depends on PNP
 * 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  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:
 *   
 * If you don't have this card, of course say N.

 * Option: NET_ETHERNET
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Ethernet (10 or 100Mbit)
 * 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 Mbit/s over coaxial cable, linking computers in a chain), 10BASE-T or twisted pair (10 Mbit/s over twisted pair cable, linking computers to central hubs), 10BASE-F (10 Mbit/s over optical fiber links, using hubs), 100BASE-TX (100 Mbit/s over two twisted pair cables, using hubs), 100BASE-T4 (100 Mbit/s over 4 standard voice-grade twisted pair cables, using hubs), 100BASE-FX (100 Mbit/s over optical fiber links) [the 100BASE varieties are also known as Fast Ethernet], and Gigabit Ethernet (1 Gbit/s 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 . 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.


 * Option: MII
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Generic Media Independent Interface device support

 * Questions concerning this driver can be addressed to: <linux@syskonnect.de>
 * To compile this driver as a module, choose M here: the module will be called skfp. This is recommended.


 * Option: HIPPI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) HIPPI driver support (EXPERIMENTAL)
 * depends on EXPERIMENTAL && INET && PCI
 * HIgh Performance Parallel Interface (HIPPI) is a 800Mbit/sec and 1600Mbit/sec dual-simplex switched or point-to-point network. HIPPI can run over copper (25m) or fiber (300m on multi-mode or 10 km on single-mode). HIPPI networks are commonly used for clusters and to connect to super computers. If you are connected to a HIPPI network and have a HIPPI network card in your computer that you want to use under Linux, say Y here (you must also remember to enable the driver for your HIPPI card below). Most people will say N here.


 * Option: ROADRUNNER
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Essential RoadRunner HIPPI PCI adapter support (EXPERIMENTAL)
 * depends on HIPPI && PCI
 * Say Y here if this is your PCI HIPPI network card.
 * To compile this driver as a module, choose M here: the module will be called rrunner. If unsure, say N.


 * Option: ROADRUNNER_LARGE_RINGS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Use large TX/RX rings (EXPERIMENTAL)
 * depends on ROADRUNNER
 * If you say Y here, the RoadRunner driver will preallocate up to 2 MB of additional memory to allow for fastest operation, both for transmitting and receiving. This memory cannot be used by any other kernel code or by user space programs. Say Y here only if you have the memory.


 * Option: PLIP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PLIP (parallel port) support
 * depends on PARPORT
 * PLIP (Parallel Line Internet Protocol) is used to create a reasonably fast mini network consisting of two (or, rarely, more) local machines. A PLIP link from a Linux box is a popular means to install a Linux distribution on a machine which doesn't have a CD-ROM drive (a minimal system has to be transferred with floppies first). The kernels on both machines need to have this PLIP option enabled for this to work.
 * The PLIP driver has two modes, mode 0 and mode 1. The parallel ports (the connectors at the computers with 25 holes) are connected with "null printer" or "Turbo Laplink" cables which can transmit 4 bits at a time (mode 0) or with special PLIP cables, to be used on bidirectional parallel ports only, which can transmit 8 bits at a time (mode 1); you can find the wiring of these cables in <file:Documentation/networking/PLIP.txt>.  The cables can be up to 15m long.  Mode 0 works also if one of the machines runs DOS/Windows and has some PLIP software installed, e.g. the Crynwr PLIP packet driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>) and winsock or NCSA's telnet.
 * If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well as the NET-3-HOWTO, both available from <http://www.tldp.org/docs.html#howto>. Note that the PLIP protocol has been changed and this PLIP driver won't work together with the PLIP support in Linux versions 1.0.x.  This option enlarges your kernel by about 8 KB.
 * To compile this driver as a module, choose M here and read <file:Documentation/networking/net-modules.txt>. The module will be called plip.  If unsure, say Y or M, in case you buy a laptop later.


 * Option: PPP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP (point-to-point protocol) support
 * PPP (Point to Point Protocol) is a newer and better SLIP. It serves the same purpose: sending Internet traffic over telephone (and other serial) lines.  Ask your access provider if they support it, because otherwise you can't use it; most Internet access providers these days support PPP rather than SLIP.
 * To use PPP, you need an additional program called pppd as described in the PPP-HOWTO, available at <http://www.tldp.org/docs.html#howto>. Make sure that you have the version of pppd recommended in <file:Documentation/Changes>. The PPP option enlarges your kernel by about 16 KB.
 * There are actually two versions of PPP: the traditional PPP for asynchronous lines, such as regular analog phone lines, and synchronous PPP which can be used over digital ISDN lines for example. If you want to use PPP over phone lines or other asynchronous serial lines, you need to say Y (or M) here and also to the next option, "PPP support for async serial ports".  For PPP over synchronous lines, you should say Y (or M) here and to "Support synchronous PPP", below.
 * If you said Y to "Version information on all symbols" above, then you cannot compile the PPP driver into the kernel; you can then only compile it as a module. To compile this driver as a module, choose M here and read <file:Documentation/networking/net-modules.txt>. The module will be called ppp_generic.


 * Option: PPP_MULTILINK
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) PPP multilink support (EXPERIMENTAL)
 * depends on PPP && EXPERIMENTAL
 * PPP multilink is a protocol (defined in RFC 1990) which allows you to combine several (logical or physical) lines into one logical PPP connection, so that you can utilize your full bandwidth.
 * This has to be supported at the other end as well and you need a version of the pppd daemon which understands the multilink protocol.
 * If unsure, say N.


 * Option: PPP_FILTER
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) PPP filtering
 * depends on PPP
 * Say Y here if you want to be able to filter the packets passing over PPP interfaces. This allows you to control which packets count as activity (i.e. which packets will reset the idle timer or bring up a demand-dialled link) and which packets are to be dropped entirely. You need to say Y here if you wish to use the pass-filter and active-filter options to pppd.
 * If unsure, say N.


 * Option: PPP_ASYNC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP support for async serial ports
 * depends on PPP
 * select CRC_CCITT
 * Say Y (or M) here if you want to be able to use PPP over standard asynchronous serial ports, such as COM1 or COM2 on a PC. If you use a modem (not a synchronous or ISDN modem) to contact your ISP, you need this option.
 * To compile this driver as a module, choose M here.
 * If unsure, say Y.


 * Option: PPP_SYNC_TTY
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP support for sync tty ports
 * depends on PPP
 * Say Y (or M) here if you want to be able to use PPP over synchronous (HDLC) tty devices, such as the SyncLink adapter. These devices are often used for high-speed leased lines like T1/E1.
 * To compile this driver as a module, choose M here.


 * Option: PPP_DEFLATE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP Deflate compression
 * depends on PPP
 * select ZLIB_INFLATE
 * select ZLIB_DEFLATE
 * Support for the Deflate compression method for PPP, which uses the Deflate algorithm (the same algorithm that gzip uses) to compress each PPP packet before it is sent over the wire. The machine at the other end of the PPP link (usually your ISP) has to support the Deflate compression method as well for this to be useful.  Even if they don't support it, it is safe to say Y here.
 * To compile this driver as a module, choose M here.


 * Option: PPP_BSDCOMP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP BSD-Compress compression
 * depends on PPP
 * Support for the BSD-Compress compression method for PPP, which uses the LZW compression method to compress each PPP packet before it is sent over the wire. The machine at the other end of the PPP link (usually your ISP) has to support the BSD-Compress compression method as well for this to be useful. Even if they don't support it, it is safe to say Y here.
 * The PPP Deflate compression method ("PPP Deflate compression", above) is preferable to BSD-Compress, because it compresses better and is patent-free.
 * Note that the BSD compression code will always be compiled as a module; it is called bsd_comp and will show up in the directory modules once you have said "make modules". If unsure, say N.

http://pptpclient.sourceforge.net/ for information onconfiguring PPTP clients and servers to utilize this method.
 * Option: PPP_MPPE
 * Kernel Versions: 2.6.15.6 ...     tristate PPP MPPE compression (encryption) (EXPERIMENTAL)      depends on PPP && EXPERIMENTAL      select CRYPTO      select CRYPTO_SHA1      select CRYPTO_ARC4      ---help---        Support for the MPPE Encryption protocol, as employed by theMicrosoft Point-to-Point Tunneling Protocol.


 * Option: PPPOE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP over Ethernet (EXPERIMENTAL)
 * depends on EXPERIMENTAL && PPP
 * Support for PPP over Ethernet.
 * This driver requires the latest version of pppd from the CVS repository at cvs.samba.org. Alternatively, see the  RoaringPenguin package (<http://www.roaringpenguin.com/pppoe>) which contains instruction on how to use this driver (under  the heading "Kernel mode PPPoE").


 * Option: PPPOATM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) PPP over ATM
 * depends on ATM && PPP
 * Support PPP (Point to Point Protocol) encapsulated in ATM frames. This implementation does not yet comply with section 8 of RFC2364, which can lead to bad results if the ATM peer loses state and changes its encapsulation unilaterally.


 * Option: SLIP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) SLIP (serial line) support
 * Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to connect to your Internet service provider or to connect to some other local Unix box or if you want to configure your Linux box as a Slip/CSlip server for other people to dial in. SLIP (Serial Line Internet Protocol) is a protocol used to send Internet traffic over serial connections such as telephone lines or null modem cables; nowadays, the protocol PPP is more commonly used for this same purpose.
 * Normally, your access provider has to support SLIP in order for you to be able to use it, but there is now a SLIP emulator called SLiRP around (available from <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which allows you to use SLIP over a regular dial up shell connection. If you plan to use SLiRP, make sure to say Y to CSLIP, below. The NET-3-HOWTO, available from <http://www.tldp.org/docs.html#howto>, explains how to configure SLIP. Note that you don't need this option if you just want to run term (term is a program which gives you almost full Internet connectivity if you have a regular dial up shell account on some Internet connected Unix computer. Read <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP support will enlarge your kernel by about 4 KB. If unsure, say N.
 * To compile this driver as a module, choose M here and read <file:Documentation/networking/net-modules.txt>. The module will be called slip.


 * Option: SLIP_COMPRESSED
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) CSLIP compressed headers
 * depends on SLIP
 * This protocol is faster than SLIP because it uses compression on the TCP/IP headers (not on the data itself), but it has to be supported on both ends. Ask your access provider if you are not sure and answer Y, just in case. You will still be able to use plain SLIP. If you plan to use SLiRP, the SLIP emulator (available from <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which allows you to use SLIP over a regular dial up shell connection, you definitely want to say Y here. The NET-3-HOWTO, available from <http://www.tldp.org/docs.html#howto>, explains how to configure CSLIP. This won't enlarge your kernel.


 * Option: SLIP_SMART
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Keepalive and linefill
 * depends on SLIP
 * Adds additional capabilities to the SLIP driver to support the RELCOM line fill and keepalive monitoring. Ideal on poor quality analogue lines.


 * Option: SLIP_MODE_SLIP6
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Six bit SLIP encapsulation
 * depends on SLIP
 * Just occasionally you may need to run IP over hostile serial networks that don't pass all control characters or are only seven bit. Saying Y here adds an extra mode you can use with SLIP: slip6. In this mode, SLIP will only send normal ASCII symbols over the serial device. Naturally, this has to be supported at the other end of the link as well. It's good enough, for example, to run IP over the async ports of a Camtec JNT Pad. If unsure, say N.


 * Option: NET_FC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Fibre Channel driver support
 * depends on SCSI && PCI
 * 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.


 * Option: SHAPER
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Traffic Shaper (EXPERIMENTAL)
 * depends on EXPERIMENTAL
 * The traffic shaper is a virtual network device that allows you to limit the rate of outgoing data flow over some other network device. The traffic that you want to slow down can then be routed through these virtual devices. See <file:Documentation/networking/shaper.txt> for more information.
 * An alternative to this traffic shaper is the experimental Class-Based Queueing (CBQ) scheduling support which you get if you say Y to "QoS and/or fair queueing" above.
 * To set up and configure shaper devices, you need the shapecfg program, available from <ftp://shadow.cabi.net/pub/Linux/> in the shaper package.
 * To compile this driver as a module, choose M here: the module will be called shaper. If unsure, say N.
