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.
33 bool "Network core driver support"
35 You can say N here if you do not intend to use any of the
36 networking core drivers (i.e. VLAN, bridging, bonding, etc.)
41 tristate "Bonding driver support"
43 depends on IPV6 || IPV6=n
45 Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
46 Channels together. This is called 'Etherchannel' by Cisco,
47 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
49 The driver supports multiple bonding modes to allow for both high
50 performance and high availability operation.
52 Refer to <file:Documentation/networking/bonding.txt> for more
55 To compile this driver as a module, choose M here: the module
56 will be called bonding.
59 tristate "Dummy net driver support"
61 This is essentially a bit-bucket device (i.e. traffic you send to
62 this device is consigned into oblivion) with a configurable IP
63 address. It is most commonly used in order to make your currently
64 inactive SLIP address seem like a real address for local programs.
65 If you use SLIP or PPP, you might want to say Y here. Since this
66 thing often comes in handy, the default is Y. It won't enlarge your
67 kernel either. What a deal. Read about it in the Network
68 Administrator's Guide, available from
69 <http://www.tldp.org/docs.html#guide>.
71 To compile this driver as a module, choose M here: the module
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 "Intermediate Functional Block support"
108 depends on NET_CLS_ACT
110 This is an intermediate driver that allows sharing of
112 To compile this driver as a module, choose M here: the module
113 will be called ifb. If you want to use more than one ifb
114 device at a time, you need to compile this driver as a module.
115 Instead of 'ifb', the devices will then be called 'ifb0',
117 Look at the iproute2 documentation directory for usage etc
119 source "drivers/net/team/Kconfig"
122 tristate "MAC-VLAN support"
124 This allows one to create virtual interfaces that map packets to
125 or from specific MAC addresses to a particular interface.
127 Macvlan devices can be added using the "ip" command from the
128 iproute2 package starting with the iproute2-2.6.23 release:
130 "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
132 To compile this driver as a module, choose M here: the module
133 will be called macvlan.
136 tristate "MAC-VLAN based tap driver"
140 This adds a specialized tap character device driver that is based
141 on the MAC-VLAN network interface, called macvtap. A macvtap device
142 can be added in the same way as a macvlan device, using 'type
143 macvtap', and then be accessed through the tap user space interface.
145 To compile this driver as a module, choose M here: the module
146 will be called macvtap.
149 tristate "Virtual eXtensible Local Area Network (VXLAN)"
151 select NET_UDP_TUNNEL
153 This allows one to create vxlan virtual interfaces that provide
154 Layer 2 Networks over Layer 3 Networks. VXLAN is often used
155 to tunnel virtual network infrastructure in virtualized environments.
156 For more information see:
157 http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02
159 To compile this driver as a module, choose M here: the module
160 will be called vxlan.
163 tristate "Network console logging support"
165 If you want to log kernel messages over the network, enable this.
166 See <file:Documentation/networking/netconsole.txt> for details.
168 config NETCONSOLE_DYNAMIC
169 bool "Dynamic reconfiguration of logging targets"
170 depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
171 !(NETCONSOLE=y && CONFIGFS_FS=m)
173 This option enables the ability to dynamically reconfigure target
174 parameters (interface, IP addresses, port numbers, MAC addresses)
175 at runtime through a userspace interface exported using configfs.
176 See <file:Documentation/networking/netconsole.txt> for details.
181 config NET_POLL_CONTROLLER
185 tristate "Virtual Ethernet over NTB"
189 tristate "RapidIO Ethernet over messaging driver support"
192 config RIONET_TX_SIZE
193 int "Number of outbound queue entries"
197 config RIONET_RX_SIZE
198 int "Number of inbound queue entries"
203 tristate "Universal TUN/TAP device driver support"
207 TUN/TAP provides packet reception and transmission for user space
208 programs. It can be viewed as a simple Point-to-Point or Ethernet
209 device, which instead of receiving packets from a physical media,
210 receives them from user space program and instead of sending packets
211 via physical media writes them to the user space program.
213 When a program opens /dev/net/tun, driver creates and registers
214 corresponding net device tunX or tapX. After a program closed above
215 devices, driver will automatically delete tunXX or tapXX device and
216 all routes corresponding to it.
218 Please read <file:Documentation/networking/tuntap.txt> for more
221 To compile this driver as a module, choose M here: the module
224 If you don't know what to use this for, you don't need it.
227 tristate "Virtual ethernet pair device"
229 This device is a local ethernet tunnel. Devices are created in pairs.
230 When one end receives the packet it appears on its pair and vice
234 tristate "Virtio network driver"
238 This is the virtual network driver for virtio. It can be used with
239 lguest or QEMU based VMMs (like KVM or Xen). Say Y or M.
242 tristate "Virtual netlink monitoring device"
244 This option enables a monitoring net device for netlink skbs. The
245 purpose of this is to analyze netlink messages with packet sockets.
246 Thus applications like tcpdump will be able to see local netlink
247 messages if they tap into the netlink device, record pcaps for further
248 diagnostics, etc. This is mostly intended for developers or support
249 to debug netlink issues. If unsure, say N.

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

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