# # Network device configuration # 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 .

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. 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 . 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 . 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. 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 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. 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 source "drivers/net/team/Kconfig" 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 [ 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 VXLAN tristate "Virtual eXtensible Local Area Network (VXLAN)" depends on EXPERIMENTAL && INET ---help--- 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 will be called vxlan. config NETCONSOLE tristate "Network console logging support" depends on !PREEMPT_RT_FULL ---help--- If you want to log kernel messages over the network, enable this. See for details. config NETCONSOLE_DYNAMIC bool "Dynamic reconfiguration of logging targets" depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \ !(NETCONSOLE=y && CONFIGFS_FS=m) help This option enables the ability to dynamically reconfigure target parameters (interface, IP addresses, port numbers, MAC addresses) at runtime through a userspace interface exported using configfs.

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. 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 VIRTIO_NET tristate "Virtio network driver (EXPERIMENTAL)" depends on EXPERIMENTAL && VIRTIO ---help--- 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. endif # NET_CORE config SUNGEM_PHY tristate source "drivers/net/arcnet/Kconfig" source "drivers/atm/Kconfig" source "drivers/net/caif/Kconfig" source "drivers/net/dsa/Kconfig" source "drivers/net/ethernet/Kconfig" source "drivers/net/fddi/Kconfig" source "drivers/net/hippi/Kconfig" 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 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. source "drivers/net/phy/Kconfig" source "drivers/net/plip/Kconfig" source "drivers/net/ppp/Kconfig" source "drivers/net/slip/Kconfig" source "drivers/s390/net/Kconfig" source "drivers/net/usb/Kconfig" source "drivers/net/wireless/Kconfig" source "drivers/net/wimax/Kconfig" source "drivers/net/wan/Kconfig" source "drivers/net/ieee802154/Kconfig" config XEN_NETDEV_FRONTEND tristate "Xen network device frontend driver" depends on XEN select XEN_XENBUS_FRONTEND default y help This driver provides support for Xen paravirtual network devices exported by a Xen network driver domain (often domain 0). 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.
