2 # Network device configuration
8 bool "Network device support"
10 You can say N here if you don't intend to connect your Linux box to
11 any other computer at all.
13 You'll have to say Y if your computer contains a network card that
14 you want to use under Linux. If you are going to run SLIP or PPP over
15 telephone line or null modem cable you need say Y here. Connecting
16 two machines with parallel ports using PLIP needs this, as well as
17 AX.25/KISS for sending Internet traffic over amateur radio links.
19 See also "The Linux Network Administrator's Guide" by Olaf Kirch and
20 Terry Dawson. Available at <http://www.tldp.org/guides.html>.
24 # All the following symbols are dependent on NETDEVICES - do not repeat
25 # that for each of the symbols.
30 bool "Network core driver support"
32 You can say N here if you do not intend to use any of the
33 networking core drivers (i.e. VLAN, bridging, bonding, etc.)
38 tristate "Bonding driver support"
40 depends on IPV6 || IPV6=n
42 Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
43 Channels together. This is called 'Etherchannel' by Cisco,
44 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
46 The driver supports multiple bonding modes to allow for both high
47 performance and high availability operation.
49 Refer to <file:Documentation/networking/bonding.txt> for more
52 To compile this driver as a module, choose M here: the module
53 will be called bonding.
56 tristate "Dummy net driver support"
58 This is essentially a bit-bucket device (i.e. traffic you send to
59 this device is consigned into oblivion) with a configurable IP
60 address. It is most commonly used in order to make your currently
61 inactive SLIP address seem like a real address for local programs.
62 If you use SLIP or PPP, you might want to say Y here. Since this
63 thing often comes in handy, the default is Y. It won't enlarge your
64 kernel either. What a deal. Read about it in the Network
65 Administrator's Guide, available from
66 <http://www.tldp.org/docs.html#guide>.
68 To compile this driver as a module, choose M here: the module
72 tristate "EQL (serial line load balancing) support"
74 If you have two serial connections to some other computer (this
75 usually requires two modems and two telephone lines) and you use
76 SLIP (the protocol for sending Internet traffic over telephone
77 lines) or PPP (a better SLIP) on them, you can make them behave like
78 one double speed connection using this driver. Naturally, this has
79 to be supported at the other end as well, either with a similar EQL
80 Linux driver or with a Livingston Portmaster 2e.
82 Say Y if you want this and read
83 <file:Documentation/networking/eql.txt>. You may also want to read
84 section 6.2 of the NET-3-HOWTO, available from
85 <http://www.tldp.org/docs.html#howto>.
87 To compile this driver as a module, choose M here: the module
88 will be called eql. If unsure, say N.
91 bool "Fibre Channel driver support"
92 depends on SCSI && PCI
94 Fibre Channel is a high speed serial protocol mainly used to connect
95 large storage devices to the computer; it is compatible with and
96 intended to replace SCSI.
98 If you intend to use Fibre Channel, you need to have a Fibre channel
99 adaptor card in your computer; say Y here and to the driver for your
100 adaptor below. You also should have said Y to "SCSI support" and
101 "SCSI generic support".
104 tristate "Generic Media Independent Interface device support"
106 Most ethernet controllers have MII transceiver either as an external
107 or internal device. It is safe to say Y or M here even if your
108 ethernet card lacks MII.
111 tristate "Intermediate Functional Block support"
112 depends on NET_CLS_ACT
114 This is an intermediate driver that allows sharing of
116 To compile this driver as a module, choose M here: the module
117 will be called ifb. If you want to use more than one ifb
118 device at a time, you need to compile this driver as a module.
119 Instead of 'ifb', the devices will then be called 'ifb0',
121 Look at the iproute2 documentation directory for usage etc
123 source "drivers/net/team/Kconfig"
126 tristate "MAC-VLAN support"
128 This allows one to create virtual interfaces that map packets to
129 or from specific MAC addresses to a particular interface.
131 Macvlan devices can be added using the "ip" command from the
132 iproute2 package starting with the iproute2-2.6.23 release:
134 "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
136 To compile this driver as a module, choose M here: the module
137 will be called macvlan.
140 tristate "MAC-VLAN based tap driver"
143 This adds a specialized tap character device driver that is based
144 on the MAC-VLAN network interface, called macvtap. A macvtap device
145 can be added in the same way as a macvlan device, using 'type
146 macvlan', and then be accessed through the tap user space interface.
148 To compile this driver as a module, choose M here: the module
149 will be called macvtap.
152 tristate "Virtual eXtensible Local Area Network (VXLAN)"
153 depends on EXPERIMENTAL && INET
155 This allows one to create vxlan virtual interfaces that provide
156 Layer 2 Networks over Layer 3 Networks. VXLAN is often used
157 to tunnel virtual network infrastructure in virtualized environments.
158 For more information see:
159 http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02
161 To compile this driver as a module, choose M here: the module
162 will be called vxlan.
165 tristate "Network console logging support"
167 If you want to log kernel messages over the network, enable this.
168 See <file:Documentation/networking/netconsole.txt> for details.
170 config NETCONSOLE_DYNAMIC
171 bool "Dynamic reconfiguration of logging targets"
172 depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
173 !(NETCONSOLE=y && CONFIGFS_FS=m)
175 This option enables the ability to dynamically reconfigure target
176 parameters (interface, IP addresses, port numbers, MAC addresses)
177 at runtime through a userspace interface exported using configfs.
178 See <file:Documentation/networking/netconsole.txt> for details.
184 bool "Netpoll traffic trapping"
188 config NET_POLL_CONTROLLER
192 tristate "Virtual Ethernet over NTB"
196 tristate "RapidIO Ethernet over messaging driver support"
199 config RIONET_TX_SIZE
200 int "Number of outbound queue entries"
204 config RIONET_RX_SIZE
205 int "Number of inbound queue entries"
210 tristate "Universal TUN/TAP device driver support"
213 TUN/TAP provides packet reception and transmission for user space
214 programs. It can be viewed as a simple Point-to-Point or Ethernet
215 device, which instead of receiving packets from a physical media,
216 receives them from user space program and instead of sending packets
217 via physical media writes them to the user space program.
219 When a program opens /dev/net/tun, driver creates and registers
220 corresponding net device tunX or tapX. After a program closed above
221 devices, driver will automatically delete tunXX or tapXX device and
222 all routes corresponding to it.
224 Please read <file:Documentation/networking/tuntap.txt> for more
227 To compile this driver as a module, choose M here: the module
230 If you don't know what to use this for, you don't need it.
233 tristate "Virtual ethernet pair device"
235 This device is a local ethernet tunnel. Devices are created in pairs.
236 When one end receives the packet it appears on its pair and vice
240 tristate "Virtio network driver"
243 This is the virtual network driver for virtio. It can be used with
244 lguest or QEMU based VMMs (like KVM or Xen). Say Y or M.

266 tristate "General Instruments Surfboard 1000"
269 This is a driver for the General Instrument (also known as
270 NextLevel) SURFboard 1000 internal
271 cable modem. This is an ISA card which is used by a number of cable
272 TV companies to provide cable modem access. It's a one-way
273 downstream-only cable modem, meaning that your upstream net link is
274 provided by your regular phone modem.
276 At present this driver only compiles as a module, so say M here if
277 you have this card. The module will be called sb1000. Then read
278 <file:Documentation/networking/README.sb1000> for information on how
279 to use this module, as it needs special ppp scripts for establishing
280 a connection. Further documentation and the necessary scripts can be

315 This driver provides support for Xen paravirtual network
316 devices exported by a Xen network driver domain (often
319 The corresponding Linux backend driver is enabled by the
320 CONFIG_XEN_NETDEV_BACKEND option.
322 If you are compiling a kernel for use as Xen guest, you
323 should say Y here. To compile this driver as a module, chose
324 M here: the module will be called xen-netfront.
326 config XEN_NETDEV_BACKEND
327 tristate "Xen backend network device"
328 depends on XEN_BACKEND
330 This driver allows the kernel to act as a Xen network driver
331 domain which exports paravirtual network devices to other
332 Xen domains. These devices can be accessed by any operating
333 system that implements a compatible front end.
335 The corresponding Linux frontend driver is enabled by the
336 CONFIG_XEN_NETDEV_FRONTEND configuration option.
338 The backend driver presents a standard network device
339 endpoint for each paravirtual network device to the driver
340 domain network stack. These can then be bridged or routed
341 etc in order to provide full network connectivity.
343 If you are compiling a kernel to run in a Xen network driver
344 domain (often this is domain 0) you should say Y here. To
345 compile this driver as a module, chose M here: the module
346 will be called xen-netback.
349 tristate "VMware VMXNET3 ethernet driver"
350 depends on PCI && INET
352 This driver supports VMware's vmxnet3 virtual ethernet NIC.
