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>.

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

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>.

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>.

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".

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.

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.

156      on packets. All interfaces (including the main interface) share L2
157      making it transparent to the connected L2 switch.

249	---help---
250	  TUN/TAP provides packet reception and transmission for user space
251	  programs.  It can be viewed as a simple Point-to-Point or Ethernet
252	  device, which instead of receiving packets from a physical media,
253	  receives them from user space program and instead of sending packets
254	  via physical media writes them to the user space program.
255
256	  When a program opens /dev/net/tun, driver creates and registers
257	  corresponding net device tunX or tapX.  After a program closed above
258	  devices, driver will automatically delete tunXX or tapXX device and
259	  all routes corresponding to it.

275	  big-endian legacy virtio device.
276
277	  Userspace programs can control the feature using the TUNSETVNETBE

300	  This option enables a monitoring net device for netlink skbs. The
301	  purpose of this is to analyze netlink messages with packet sockets.
302	  Thus applications like tcpdump will be able to see local netlink
303	  messages if they tap into the netlink device, record pcaps for further
304	  diagnostics, etc. This is mostly intended for developers or support
