9	---help---
10	  You can say N here if you don't intend to connect your Linux box to
11	  any other computer at all.
12
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.
18
19	  See also "The Linux Network Administrator's Guide" by Olaf Kirch and
20	  Terry Dawson. Available at <http://www.tldp.org/guides.html>.
21
22	  If unsure, say Y.

37config BONDING
38	tristate "Bonding driver support"
39	depends on INET
40	depends on IPV6 || IPV6=n
41	---help---
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.
45
46	  The driver supports multiple bonding modes to allow for both high
47	  performance and high availability operation.
48
49	  Refer to <file:Documentation/networking/bonding.txt> for more
50	  information.
51
52	  To compile this driver as a module, choose M here: the module
53	  will be called bonding.
54
55config DUMMY
56	tristate "Dummy net driver support"
57	---help---
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>.
67
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',
72	  'dummy1' etc.
73
74config EQUALIZER
75	tristate "EQL (serial line load balancing) support"
76	---help---
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.
84
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>.
89
90	  To compile this driver as a module, choose M here: the module
91	  will be called eql.  If unsure, say N.
92
93config NET_FC
94	bool "Fibre Channel driver support"
95	depends on SCSI && PCI
96	help
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.
100
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".
105
106config MII
107	tristate "Generic Media Independent Interface device support"
108	help
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.

115config IFB
116	tristate "Intermediate Functional Block support"
117	depends on NET_CLS_ACT
118	---help---
119	  This is an intermediate driver that allows sharing of
120	  resources.
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',
125	  'ifb1' etc.
126	  Look at the iproute2 documentation directory for usage etc
127
128config MACVLAN
129	tristate "MAC-VLAN support (EXPERIMENTAL)"
130	depends on EXPERIMENTAL
131	---help---
132	  This allows one to create virtual interfaces that map packets to
133	  or from specific MAC addresses to a particular interface.
134
135	  Macvlan devices can be added using the "ip" command from the
136	  iproute2 package starting with the iproute2-2.6.23 release:
137
138	  "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
139
140	  To compile this driver as a module, choose M here: the module
141	  will be called macvlan.
142
143config MACVTAP
144	tristate "MAC-VLAN based tap driver (EXPERIMENTAL)"
145	depends on MACVLAN
146	help
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.
151

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.

196config TUN
197	tristate "Universal TUN/TAP device driver support"
198	select CRC32
199	---help---
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.
205
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.
210
211	  Please read <file:Documentation/networking/tuntap.txt> for more
212	  information.
213
214	  To compile this driver as a module, choose M here: the module
215	  will be called tun.

219config VETH

222	  This device is a local ethernet tunnel. Devices are created in pairs.

251	---help---
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.
258
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
