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. It won't
66 enlarge your kernel. What a deal. Read about it in the Network
67 Administrator's Guide, available from
68 <http://www.tldp.org/docs.html#guide>.
70 To compile this driver as a module, choose M here: the module
74 tristate "EQL (serial line load balancing) support"
76 If you have two serial connections to some other computer (this
77 usually requires two modems and two telephone lines) and you use
78 SLIP (the protocol for sending Internet traffic over telephone
79 lines) or PPP (a better SLIP) on them, you can make them behave like
80 one double speed connection using this driver. Naturally, this has
81 to be supported at the other end as well, either with a similar EQL
82 Linux driver or with a Livingston Portmaster 2e.
84 Say Y if you want this and read
85 <file:Documentation/networking/eql.txt>. You may also want to read
86 section 6.2 of the NET-3-HOWTO, available from
87 <http://www.tldp.org/docs.html#howto>.
89 To compile this driver as a module, choose M here: the module
90 will be called eql. If unsure, say N.
93 bool "Fibre Channel driver support"
94 depends on SCSI && PCI
96 Fibre Channel is a high speed serial protocol mainly used to connect
97 large storage devices to the computer; it is compatible with and
98 intended to replace SCSI.
100 If you intend to use Fibre Channel, you need to have a Fibre channel
101 adaptor card in your computer; say Y here and to the driver for your
102 adaptor below. You also should have said Y to "SCSI support" and
103 "SCSI generic support".
106 tristate "Intermediate Functional Block support"
107 depends on NET_CLS_ACT
109 This is an intermediate driver that allows sharing of
111 To compile this driver as a module, choose M here: the module
112 will be called ifb. If you want to use more than one ifb
113 device at a time, you need to compile this driver as a module.
114 Instead of 'ifb', the devices will then be called 'ifb0',
116 Look at the iproute2 documentation directory for usage etc
118 source "drivers/net/team/Kconfig"
121 tristate "MAC-VLAN support"
123 This allows one to create virtual interfaces that map packets to
124 or from specific MAC addresses to a particular interface.
126 Macvlan devices can be added using the "ip" command from the
127 iproute2 package starting with the iproute2-2.6.23 release:
129 "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
131 To compile this driver as a module, choose M here: the module
132 will be called macvlan.
135 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.
152 select NET_L3_MASTER_DEV
155 tristate "IP-VLAN support"
157 depends on IPV6 || !IPV6
159 This allows one to create virtual devices off of a main interface
160 and packets will be delivered based on the dest L3 (IPv6/IPv4 addr)
161 on packets. All interfaces (including the main interface) share L2
162 making it transparent to the connected L2 switch.
164 Ipvlan devices can be added using the "ip" command from the
165 iproute2 package starting with the iproute2-3.19 release:
167 "ip link add link <main-dev> [ NAME ] type ipvlan"
169 To compile this driver as a module, choose M here: the module
170 will be called ipvlan.
173 tristate "IP-VLAN based tap driver"
178 This adds a specialized tap character device driver that is based
179 on the IP-VLAN network interface, called ipvtap. An ipvtap device
180 can be added in the same way as a ipvlan device, using 'type
181 ipvtap', and then be accessed through the tap user space interface.
183 To compile this driver as a module, choose M here: the module
184 will be called ipvtap.
187 tristate "Virtual eXtensible Local Area Network (VXLAN)"
189 select NET_UDP_TUNNEL
192 This allows one to create vxlan virtual interfaces that provide
193 Layer 2 Networks over Layer 3 Networks. VXLAN is often used
194 to tunnel virtual network infrastructure in virtualized environments.
195 For more information see:
196 http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02
198 To compile this driver as a module, choose M here: the module
199 will be called vxlan.
202 tristate "Generic Network Virtualization Encapsulation"
204 depends on IPV6 || !IPV6
205 select NET_UDP_TUNNEL
208 This allows one to create geneve virtual interfaces that provide
209 Layer 2 Networks over Layer 3 Networks. GENEVE is often used
210 to tunnel virtual network infrastructure in virtualized environments.
211 For more information see:
212 http://tools.ietf.org/html/draft-gross-geneve-02
214 To compile this driver as a module, choose M here: the module
215 will be called geneve.
218 tristate "GPRS Tunneling Protocol datapath (GTP-U)"
219 depends on INET && NET_UDP_TUNNEL
222 This allows one to create gtp virtual interfaces that provide
223 the GPRS Tunneling Protocol datapath (GTP-U). This tunneling protocol
224 is used to prevent subscribers from accessing mobile carrier core
225 network infrastructure. This driver requires a userspace software that
226 implements the signaling protocol (GTP-C) to update its PDP context
227 base, such as OpenGGSN <http://git.osmocom.org/openggsn/). This
228 tunneling protocol is implemented according to the GSM TS 09.60 and
229 3GPP TS 29.060 standards.

235 tristate "IEEE 802.1AE MAC-level encryption (MACsec)"
241 MACsec is an encryption standard for Ethernet.
244 tristate "Network console logging support"
246 If you want to log kernel messages over the network, enable this.
247 See <file:Documentation/networking/netconsole.txt> for details.
249 config NETCONSOLE_DYNAMIC
250 bool "Dynamic reconfiguration of logging targets"
251 depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
252 !(NETCONSOLE=y && CONFIGFS_FS=m)
254 This option enables the ability to dynamically reconfigure target
255 parameters (interface, IP addresses, port numbers, MAC addresses)
256 at runtime through a userspace interface exported using configfs.
257 See <file:Documentation/networking/netconsole.txt> for details.

275 int "Number of outbound queue entries"
279 config RIONET_RX_SIZE
280 int "Number of inbound queue entries"
285 tristate "Universal TUN/TAP device driver support"
289 TUN/TAP provides packet reception and transmission for user space
290 programs. It can be viewed as a simple Point-to-Point or Ethernet
291 device, which instead of receiving packets from a physical media,
292 receives them from user space program and instead of sending packets
293 via physical media writes them to the user space program.
295 When a program opens /dev/net/tun, driver creates and registers
296 corresponding net device tunX or tapX. After a program closed above
297 devices, driver will automatically delete tunXX or tapXX device and
298 all routes corresponding to it.
300 Please read <file:Documentation/networking/tuntap.txt> for more
303 To compile this driver as a module, choose M here: the module
306 If you don't know what to use this for, you don't need it.
311 This option is selected by any driver implementing tap user space
312 interface for a virtual interface to re-use core tap functionality.
314 config TUN_VNET_CROSS_LE
315 bool "Support for cross-endian vnet headers on little-endian kernels"
318 This option allows TUN/TAP and MACVTAP device drivers in a
319 little-endian kernel to parse vnet headers that come from a
320 big-endian legacy virtio device.
322 Userspace programs can control the feature using the TUNSETVNETBE
323 and TUNGETVNETBE ioctls.
325 Unless you have a little-endian system hosting a big-endian virtual
326 machine with a legacy virtio NIC, you should say N.
329 tristate "Virtual ethernet pair device"
331 This device is a local ethernet tunnel. Devices are created in pairs.
332 When one end receives the packet it appears on its pair and vice
336 tristate "Virtio network driver"
340 This is the virtual network driver for virtio. It can be used with
341 QEMU based VMMs (like KVM or Xen). Say Y or M.
344 tristate "Virtual netlink monitoring device"
346 This option enables a monitoring net device for netlink skbs. The
347 purpose of this is to analyze netlink messages with packet sockets.
348 Thus applications like tcpdump will be able to see local netlink
349 messages if they tap into the netlink device, record pcaps for further
350 diagnostics, etc. This is mostly intended for developers or support
351 to debug netlink issues. If unsure, say N.

394 This is a driver for the General Instrument (also known as
395 NextLevel) SURFboard 1000 internal
396 cable modem. This is an ISA card which is used by a number of cable
397 TV companies to provide cable modem access. It's a one-way
398 downstream-only cable modem, meaning that your upstream net link is
399 provided by your regular phone modem.
401 At present this driver only compiles as a module, so say M here if
402 you have this card. The module will be called sb1000. Then read
403 <file:Documentation/networking/device_drivers/sb1000.txt> for
404 information on how to use this module, as it needs special ppp
405 scripts for establishing a connection. Further documentation

441 devices exported by a Xen network driver domain (often
444 The corresponding Linux backend driver is enabled by the
445 CONFIG_XEN_NETDEV_BACKEND option.
447 If you are compiling a kernel for use as Xen guest, you
448 should say Y here. To compile this driver as a module, chose
449 M here: the module will be called xen-netfront.
451 config XEN_NETDEV_BACKEND
452 tristate "Xen backend network device"
453 depends on XEN_BACKEND
455 This driver allows the kernel to act as a Xen network driver
456 domain which exports paravirtual network devices to other
457 Xen domains. These devices can be accessed by any operating
458 system that implements a compatible front end.
460 The corresponding Linux frontend driver is enabled by the
461 CONFIG_XEN_NETDEV_FRONTEND configuration option.
463 The backend driver presents a standard network device
464 endpoint for each paravirtual network device to the driver
465 domain network stack. These can then be bridged or routed
466 etc in order to provide full network connectivity.
468 If you are compiling a kernel to run in a Xen network driver
469 domain (often this is domain 0) you should say Y here. To

514 will be called netdevsim.
517 tristate "Failover driver"
520 This provides an automated failover mechanism via APIs to create
521 and destroy a failover master netdev and manages a primary and
522 standby slave netdevs that get registered via the generic failover
523 infrastructure. This can be used by paravirtual drivers to enable
524 an alternate low latency datapath. It also enables live migration of
525 a VM with direct attached VF by failing over to the paravirtual
526 datapath when the VF is unplugged.
