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>.

40config BONDING
41	tristate "Bonding driver support"
42	depends on INET
43	depends on IPV6 || IPV6=n
44	---help---
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.
48
49	  The driver supports multiple bonding modes to allow for both high
50	  performance and high availability operation.
51
52	  Refer to <file:Documentation/networking/bonding.txt> for more
53	  information.
54
55	  To compile this driver as a module, choose M here: the module
56	  will be called bonding.

58config DUMMY
59	tristate "Dummy net driver support"
60	---help---
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>.
70
71	  To compile this driver as a module, choose M here: the module
72	  will be called dummy.

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>.

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".

108	depends on NET_CLS_ACT
109	---help---
110	  This is an intermediate driver that allows sharing of
111	  resources.
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',
116	  'ifb1' etc.

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

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

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

238
239config NLMON
240	tristate "Virtual netlink monitoring device"
241	---help---
242	  This option enables a monitoring net device for netlink skbs. The
243	  purpose of this is to analyze netlink messages with packet sockets.
244	  Thus applications like tcpdump will be able to see local netlink
245	  messages if they tap into the netlink device, record pcaps for further
246	  diagnostics, etc. This is mostly intended for developers or support
247	  to debug netlink issues. If unsure, say N.

272	  This is a driver for the General Instrument (also known as
273	  NextLevel) SURFboard 1000 internal
274	  cable modem. This is an ISA card which is used by a number of cable
275	  TV companies to provide cable modem access. It's a one-way
