9 bool "Network device support"
11 You can say N here if you don't intend to connect your Linux box to
12 any other computer at all.
14 You'll have to say Y if your computer contains a network card that
15 you want to use under Linux. If you are going to run SLIP or PPP over
16 telephone line or null modem cable you need say Y here. Connecting
17 two machines with parallel ports using PLIP needs this, as well as
18 AX.25/KISS for sending Internet traffic over amateur radio links.

34 bool "Network core driver support"
36 You can say N here if you do not intend to use any of the
37 networking core drivers (i.e. VLAN, bridging, bonding, etc.)
42 tristate "Bonding driver support"
44 depends on IPV6 || IPV6=n
46 Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
47 Channels together. This is called 'Etherchannel' by Cisco,
48 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
50 The driver supports multiple bonding modes to allow for both high
51 performance and high availability operation.
53 Refer to <file:Documentation/networking/bonding.txt> for more
56 To compile this driver as a module, choose M here: the module
57 will be called bonding.
60 tristate "Dummy net driver support"
62 This is essentially a bit-bucket device (i.e. traffic you send to
63 this device is consigned into oblivion) with a configurable IP
64 address. It is most commonly used in order to make your currently
65 inactive SLIP address seem like a real address for local programs.
66 If you use SLIP or PPP, you might want to say Y here. It won't
67 enlarge your kernel. What a deal. Read about it in the Network
68 Administrator's Guide, available from
69 <http://www.tldp.org/docs.html#guide>.

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".

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"
141 This adds a specialized tap character device driver that is based
142 on the MAC-VLAN network interface, called macvtap. A macvtap device
143 can be added in the same way as a macvlan device, using 'type
144 macvtap', and then be accessed through the tap user space interface.
146 To compile this driver as a module, choose M here: the module
147 will be called macvtap.
153 select NET_L3_MASTER_DEV
156 tristate "IP-VLAN support"
158 depends on IPV6 || !IPV6
160 This allows one to create virtual devices off of a main interface
161 and packets will be delivered based on the dest L3 (IPv6/IPv4 addr)
162 on packets. All interfaces (including the main interface) share L2
163 making it transparent to the connected L2 switch.
165 Ipvlan devices can be added using the "ip" command from the
166 iproute2 package starting with the iproute2-3.19 release:
168 "ip link add link <main-dev> [ NAME ] type ipvlan"
170 To compile this driver as a module, choose M here: the module
171 will be called ipvlan.
174 tristate "IP-VLAN based tap driver"

185 will be called ipvtap.
188 tristate "Virtual eXtensible Local Area Network (VXLAN)"
190 select NET_UDP_TUNNEL
193 This allows one to create vxlan virtual interfaces that provide
194 Layer 2 Networks over Layer 3 Networks. VXLAN is often used
195 to tunnel virtual network infrastructure in virtualized environments.
196 For more information see:

216 will be called geneve.
219 tristate "GPRS Tunneling Protocol datapath (GTP-U)"
221 select NET_UDP_TUNNEL
223 This allows one to create gtp virtual interfaces that provide
224 the GPRS Tunneling Protocol datapath (GTP-U). This tunneling protocol
225 is used to prevent subscribers from accessing mobile carrier core
226 network infrastructure. This driver requires a userspace software that
227 implements the signaling protocol (GTP-C) to update its PDP context
228 base, such as OpenGGSN <http://git.osmocom.org/openggsn/). This
229 tunneling protocol is implemented according to the GSM TS 09.60 and
230 3GPP TS 29.060 standards.

286 tristate "Universal TUN/TAP device driver support"
290 TUN/TAP provides packet reception and transmission for user space
291 programs. It can be viewed as a simple Point-to-Point or Ethernet
292 device, which instead of receiving packets from a physical media,
293 receives them from user space program and instead of sending packets
294 via physical media writes them to the user space program.
296 When a program opens /dev/net/tun, driver creates and registers
297 corresponding net device tunX or tapX. After a program closed above
298 devices, driver will automatically delete tunXX or tapXX device and
299 all routes corresponding to it.
301 Please read <file:Documentation/networking/tuntap.txt> for more
304 To compile this driver as a module, choose M here: the module
307 If you don't know what to use this for, you don't need it.

313 interface for a virtual interface to re-use core tap functionality.
315 config TUN_VNET_CROSS_LE
316 bool "Support for cross-endian vnet headers on little-endian kernels"
319 This option allows TUN/TAP and MACVTAP device drivers in a
320 little-endian kernel to parse vnet headers that come from a
321 big-endian legacy virtio device.
323 Userspace programs can control the feature using the TUNSETVNETBE
324 and TUNGETVNETBE ioctls.
326 Unless you have a little-endian system hosting a big-endian virtual
327 machine with a legacy virtio NIC, you should say N.

341 This is the virtual network driver for virtio. It can be used with
342 QEMU based VMMs (like KVM or Xen). Say Y or M.
345 tristate "Virtual netlink monitoring device"
347 This option enables a monitoring net device for netlink skbs. The
348 purpose of this is to analyze netlink messages with packet sockets.
349 Thus applications like tcpdump will be able to see local netlink
350 messages if they tap into the netlink device, record pcaps for further
351 diagnostics, etc. This is mostly intended for developers or support
352 to debug netlink issues. If unsure, say N.

452 config XEN_NETDEV_BACKEND
453 tristate "Xen backend network device"
454 depends on XEN_BACKEND
456 This driver allows the kernel to act as a Xen network driver
457 domain which exports paravirtual network devices to other
458 Xen domains. These devices can be accessed by any operating
459 system that implements a compatible front end.
461 The corresponding Linux frontend driver is enabled by the
462 CONFIG_XEN_NETDEV_FRONTEND configuration option.
464 The backend driver presents a standard network device
465 endpoint for each paravirtual network device to the driver
466 domain network stack. These can then be bridged or routed
467 etc in order to provide full network connectivity.
469 If you are compiling a kernel to run in a Xen network driver
470 domain (often this is domain 0) you should say Y here. To

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