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.

19	  See also "The Linux Network Administrator's Guide" by Olaf Kirch and
20	  Terry Dawson. Available at <http://www.tldp.org/guides.html>.

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

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. It won't
66	  enlarge your kernel. What a deal. Read about it in the Network
67	  Administrator's Guide, available from
68	  <http://www.tldp.org/docs.html#guide>.

76	  If you have two serial connections to some other computer (this
77	  usually requires two modems and two telephone lines) and you use
78	  SLIP (the protocol for sending Internet traffic over telephone
79	  lines) or PPP (a better SLIP) on them, you can make them behave like
80	  one double speed connection using this driver.  Naturally, this has
81	  to be supported at the other end as well, either with a similar EQL
82	  Linux driver or with a Livingston Portmaster 2e.
83
84	  Say Y if you want this and read
85	  <file:Documentation/networking/eql.txt>.  You may also want to read
86	  section 6.2 of the NET-3-HOWTO, available from

96	  Fibre Channel is a high speed serial protocol mainly used to connect
97	  large storage devices to the computer; it is compatible with and
98	  intended to replace SCSI.
99
100	  If you intend to use Fibre Channel, you need to have a Fibre channel
101	  adaptor card in your computer; say Y here and to the driver for your
102	  adaptor below. You also should have said Y to "SCSI support" and
103	  "SCSI generic support".

112	  will be called ifb.  If you want to use more than one ifb
113	  device at a time, you need to compile this driver as a module.
114	  Instead of 'ifb', the devices will then be called 'ifb0',

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

202	  This allows one to create gtp virtual interfaces that provide
203	  the GPRS Tunneling Protocol datapath (GTP-U). This tunneling protocol
204	  is used to prevent subscribers from accessing mobile carrier core
205	  network infrastructure. This driver requires a userspace software that
206	  implements the signaling protocol (GTP-C) to update its PDP context
207	  base, such as OpenGGSN <http://git.osmocom.org/openggsn/). This
208	  tunneling protocol is implemented according to the GSM TS 09.60 and

268	  TUN/TAP provides packet reception and transmission for user space
269	  programs.  It can be viewed as a simple Point-to-Point or Ethernet
270	  device, which instead of receiving packets from a physical media,
271	  receives them from user space program and instead of sending packets
272	  via physical media writes them to the user space program.
273
274	  When a program opens /dev/net/tun, driver creates and registers
275	  corresponding net device tunX or tapX.  After a program closed above
