8	bool "Network device support"
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>.

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.

71config EQUALIZER
72	tristate "EQL (serial line load balancing) support"
73	---help---
74	  If you have two serial connections to some other computer (this
75	  usually requires two modems and two telephone lines) and you use
76	  SLIP (the protocol for sending Internet traffic over telephone
77	  lines) or PPP (a better SLIP) on them, you can make them behave like
78	  one double speed connection using this driver.  Naturally, this has
79	  to be supported at the other end as well, either with a similar EQL
80	  Linux driver or with a Livingston Portmaster 2e.
81
82	  Say Y if you want this and read
83	  <file:Documentation/networking/eql.txt>.  You may also want to read
84	  section 6.2 of the NET-3-HOWTO, available from
85	  <http://www.tldp.org/docs.html#howto>.
86
87	  To compile this driver as a module, choose M here: the module
88	  will be called eql.  If unsure, say N.

90config NET_FC
91	bool "Fibre Channel driver support"
92	depends on SCSI && PCI
93	help
94	  Fibre Channel is a high speed serial protocol mainly used to connect
95	  large storage devices to the computer; it is compatible with and
96	  intended to replace SCSI.
97
98	  If you intend to use Fibre Channel, you need to have a Fibre channel
99	  adaptor card in your computer; say Y here and to the driver for your
100	  adaptor below. You also should have said Y to "SCSI support" and
101	  "SCSI generic support".
102
103config MII
104	tristate "Generic Media Independent Interface device support"
105	help
106	  Most ethernet controllers have MII transceiver either as an external
107	  or internal device.  It is safe to say Y or M here even if your
108	  ethernet card lacks MII.
109
110config IFB
111	tristate "Intermediate Functional Block support"
112	depends on NET_CLS_ACT
113	---help---
114	  This is an intermediate driver that allows sharing of
115	  resources.
116	  To compile this driver as a module, choose M here: the module
117	  will be called ifb.  If you want to use more than one ifb
118	  device at a time, you need to compile this driver as a module.
119	  Instead of 'ifb', the devices will then be called 'ifb0',
120	  'ifb1' etc.
121	  Look at the iproute2 documentation directory for usage etc

126	tristate "MAC-VLAN support"
127	---help---
128	  This allows one to create virtual interfaces that map packets to
129	  or from specific MAC addresses to a particular interface.
130
131	  Macvlan devices can be added using the "ip" command from the
132	  iproute2 package starting with the iproute2-2.6.23 release:
133
134	  "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
135
136	  To compile this driver as a module, choose M here: the module
137	  will be called macvlan.
138
139config MACVTAP
140	tristate "MAC-VLAN based tap driver"
141	depends on MACVLAN
142	help
143	  This adds a specialized tap character device driver that is based
144	  on the MAC-VLAN network interface, called macvtap. A macvtap device
145	  can be added in the same way as a macvlan device, using 'type
146	  macvlan', and then be accessed through the tap user space interface.

154       ---help---
155	  This allows one to create vxlan virtual interfaces that provide
156	  Layer 2 Networks over Layer 3 Networks. VXLAN is often used
157	  to tunnel virtual network infrastructure in virtualized environments.

207	select CRC32
208	---help---
209	  TUN/TAP provides packet reception and transmission for user space
210	  programs.  It can be viewed as a simple Point-to-Point or Ethernet
211	  device, which instead of receiving packets from a physical media,
212	  receives them from user space program and instead of sending packets
213	  via physical media writes them to the user space program.
214
215	  When a program opens /dev/net/tun, driver creates and registers
216	  corresponding net device tunX or tapX.  After a program closed above
217	  devices, driver will automatically delete tunXX or tapXX device and
218	  all routes corresponding to it.
219
220	  Please read <file:Documentation/networking/tuntap.txt> for more
221	  information.

264	---help---
265	  This is a driver for the General Instrument (also known as
266	  NextLevel) SURFboard 1000 internal
267	  cable modem. This is an ISA card which is used by a number of cable
268	  TV companies to provide cable modem access. It's a one-way

270	  provided by your regular phone modem.
