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.

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
69 will be called dummy. If you want to use more than one dummy
70 device at a time, you need to compile this driver as a module.
71 Instead of 'dummy', the devices will then be called 'dummy0',
75 tristate "EQL (serial line load balancing) support"
77 If you have two serial connections to some other computer (this
78 usually requires two modems and two telephone lines) and you use
79 SLIP (the protocol for sending Internet traffic over telephone
80 lines) or PPP (a better SLIP) on them, you can make them behave like
81 one double speed connection using this driver. Naturally, this has
82 to be supported at the other end as well, either with a similar EQL
83 Linux driver or with a Livingston Portmaster 2e.
85 Say Y if you want this and read
86 <file:Documentation/networking/eql.txt>. You may also want to read
87 section 6.2 of the NET-3-HOWTO, available from
88 <http://www.tldp.org/docs.html#howto>.
90 To compile this driver as a module, choose M here: the module
91 will be called eql. If unsure, say N.
94 bool "Fibre Channel driver support"
95 depends on SCSI && PCI
97 Fibre Channel is a high speed serial protocol mainly used to connect
98 large storage devices to the computer; it is compatible with and
99 intended to replace SCSI.
101 If you intend to use Fibre Channel, you need to have a Fibre channel
102 adaptor card in your computer; say Y here and to the driver for your
103 adaptor below. You also should have said Y to "SCSI support" and
104 "SCSI generic support".
107 tristate "Generic Media Independent Interface device support"
109 Most ethernet controllers have MII transceiver either as an external
110 or internal device. It is safe to say Y or M here even if your
111 ethernet card lacks MII.
113 source "drivers/ieee802154/Kconfig"
116 tristate "Intermediate Functional Block support"
117 depends on NET_CLS_ACT
119 This is an intermediate driver that allows sharing of
121 To compile this driver as a module, choose M here: the module
122 will be called ifb. If you want to use more than one ifb
123 device at a time, you need to compile this driver as a module.
124 Instead of 'ifb', the devices will then be called 'ifb0',
126 Look at the iproute2 documentation directory for usage etc
129 tristate "MAC-VLAN support (EXPERIMENTAL)"
130 depends on EXPERIMENTAL
132 This allows one to create virtual interfaces that map packets to
133 or from specific MAC addresses to a particular interface.
135 Macvlan devices can be added using the "ip" command from the
136 iproute2 package starting with the iproute2-2.6.23 release:
138 "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
140 To compile this driver as a module, choose M here: the module
141 will be called macvlan.
144 tristate "MAC-VLAN based tap driver (EXPERIMENTAL)"
147 This adds a specialized tap character device driver that is based
148 on the MAC-VLAN network interface, called macvtap. A macvtap device
149 can be added in the same way as a macvlan device, using 'type
150 macvlan', and then be accessed through the tap user space interface.
152 To compile this driver as a module, choose M here: the module
153 will be called macvtap.
156 tristate "Network console logging support"
158 If you want to log kernel messages over the network, enable this.
159 See <file:Documentation/networking/netconsole.txt> for details.
161 config NETCONSOLE_DYNAMIC
162 bool "Dynamic reconfiguration of logging targets"
163 depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
164 !(NETCONSOLE=y && CONFIGFS_FS=m)
166 This option enables the ability to dynamically reconfigure target
167 parameters (interface, IP addresses, port numbers, MAC addresses)
168 at runtime through a userspace interface exported using configfs.
169 See <file:Documentation/networking/netconsole.txt> for details.
175 bool "Netpoll traffic trapping"
179 config NET_POLL_CONTROLLER
183 tristate "RapidIO Ethernet over messaging driver support"
186 config RIONET_TX_SIZE
187 int "Number of outbound queue entries"
191 config RIONET_RX_SIZE
192 int "Number of inbound queue entries"
197 tristate "Universal TUN/TAP device driver support"
200 TUN/TAP provides packet reception and transmission for user space
201 programs. It can be viewed as a simple Point-to-Point or Ethernet
202 device, which instead of receiving packets from a physical media,
203 receives them from user space program and instead of sending packets
204 via physical media writes them to the user space program.
206 When a program opens /dev/net/tun, driver creates and registers
207 corresponding net device tunX or tapX. After a program closed above
208 devices, driver will automatically delete tunXX or tapXX device and
209 all routes corresponding to it.
211 Please read <file:Documentation/networking/tuntap.txt> for more
214 To compile this driver as a module, choose M here: the module
217 If you don't know what to use this for, you don't need it.
220 tristate "Virtual ethernet pair device"
222 This device is a local ethernet tunnel. Devices are created in pairs.
223 When one end receives the packet it appears on its pair and vice
227 tristate "Virtio network driver (EXPERIMENTAL)"
228 depends on EXPERIMENTAL && VIRTIO
230 This is the virtual network driver for virtio. It can be used with
231 lguest or QEMU based VMMs (like KVM or Xen). Say Y or M.

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

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