[NET]: move config options out to individual protocols

Browse source 
Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.

The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.

Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

config ATALK
tristate "Appletalk protocol support"
select LLC
---help---
AppleTalk is the protocol that Apple computers can use to communicate
on a network. If your Linux box is connected to such a network and you
wish to connect to it, say Y. You will need to use the netatalk package
so that your Linux box can act as a print and file server for Macs as
well as access AppleTalk printers. Check out
<http://www.zettabyte.net/netatalk/> on the WWW for details.
EtherTalk is the name used for AppleTalk over Ethernet and the
cheaper and slower LocalTalk is AppleTalk over a proprietary Apple
network using serial links. EtherTalk and LocalTalk are fully
supported by Linux.
General information about how to connect Linux, Windows machines and
Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. The
NET-3-HOWTO, available from
<http://www.tldp.org/docs.html#howto>, contains valuable
information as well.
To compile this driver as a module, choose M here: the module will be
called appletalk. You almost certainly want to compile it as a
module so you can restart your AppleTalk stack without rebooting
your machine. I hear that the GNU boycott of Apple is over, so
even politically correct people are allowed to say Y here.

In order to participate in an ATM network, your Linux box needs an
ATM networking card. If you have that, say Y here and to the driver

IPX is similar in scope to IP, while SPX, which runs on top of IPX,
is similar to TCP. There is also experimental support for SPX in
Linux (see "SPX networking", below).
To turn your Linux box into a fully featured NetWare file server and

---help---
X.25 is a set of standardized network protocols, similar in scope to
frame relay; the one physical line from your box to the X.25 network
entry point can carry several logical point-to-point connections
(called "virtual circuits") to other computers connected to the X.25
network. Governments, banks, and other organizations tend to use it
to connect to each other or to form Wide Area Networks (WANs). Many
countries have public X.25 networks. X.25 consists of two
protocols: the higher level Packet Layer Protocol (PLP) (say Y here
if you want that) and the lower level data link layer protocol LAPB
(say Y to "LAPB Data Link Driver" below if you want that).
You can read more about X.25 at <http://www.sangoma.com/x25.htm> and
<http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm>.
Information about X.25 for Linux is contained in the files
<file:Documentation/networking/x25.txt> and
<file:Documentation/networking/x25-iface.txt>.
One connects to an X.25 network either with a dedicated network card
using the X.21 protocol (not yet supported by Linux) or one can do
X.25 over a standard telephone line using an ordinary modem (say Y
to "X.25 async driver" below) or over Ethernet using an ordinary
Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
Driver" and "LAPB over Ethernet driver" below).

Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.

it is used to transport higher level protocols (mostly X.25 Packet
Layer, the higher part of X.25, but others are possible as well).

Wide Area Networks (WANs), such as X.25, frame relay and leased

Usually, a quite expensive external device called a `WAN router' is
needed to connect to a WAN.
As an alternative, WAN routing can be built into the Linux kernel.
With relatively inexpensive WAN interface cards available on the
market, a perfectly usable router can be built for less than half
the price of an external router. If you have one of those cards and
wish to use your Linux box as a WAN router, say Y here and also to

When the kernel has several packets to send out over a network
device, it has to decide which ones to send first, which ones to
delay, and which ones to drop. This is the job of the packet
scheduler, and several different algorithms for how to do this
"fairly" have been proposed.
If you say N here, you will get the standard packet scheduler, which
is a FIFO (first come, first served). If you say Y here, you will be
able to choose from among several alternative algorithms which can
then be attached to different network devices. This is useful for
example if some of your network devices are real time devices that
need a certain minimum data flow rate, or if you need to limit the
maximum data flow rate for traffic which matches specified criteria.
This code is considered to be experimental.
To administer these schedulers, you'll need the user-level utilities
from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
That package also contains some documentation; for more, check out
<http://snafu.freedom.org/linux2.2/iproute-notes.html>.

This is support for the Novell networking protocol, IPX, commonly

want to access Novell NetWare file or print servers using the Linux
Novell client ncpfs (available from
<ftp://platan.vc.cvut.cz/pub/linux/ncpfs/>) or from
within the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO,
available from <http://www.tldp.org/docs.html#howto>). In order
to do the former, you'll also have to say Y to "NCP file system
support", below.
IPX is similar in scope to IP, while SPX, which runs on top of IPX,
is similar to TCP. There is also experimental support for SPX in
Linux (see "SPX networking", below).
To turn your Linux box into a fully featured NetWare file server and
IPX router, say Y here and fetch either lwared from
<ftp://ibiblio.org/pub/Linux/system/network/daemons/> or
mars_nwe from <ftp://www.compu-art.de/mars_nwe/>. For more

Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
the lower) part of the X.25 protocol. It offers a reliable
connection service to exchange data frames with one other host, and
it is used to transport higher level protocols (mostly X.25 Packet
Layer, the higher part of X.25, but others are possible as well).
Usually, LAPB is used with specialized X.21 network cards, but Linux
currently supports LAPB only over Ethernet connections. If you want
to use LAPB connections over Ethernet, say Y here and to "LAPB over

bool "QoS and/or fair queueing"
---help---
When the kernel has several packets to send out over a network
device, it has to decide which ones to send first, which ones to
delay, and which ones to drop. This is the job of the packet
scheduler, and several different algorithms for how to do this
"fairly" have been proposed.
If you say N here, you will get the standard packet scheduler, which
is a FIFO (first come, first served). If you say Y here, you will be
able to choose from among several alternative algorithms which can
then be attached to different network devices. This is useful for
example if some of your network devices are real time devices that
need a certain minimum data flow rate, or if you need to limit the
maximum data flow rate for traffic which matches specified criteria.
This code is considered to be experimental.
To administer these schedulers, you'll need the user-level utilities
from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
That package also contains some documentation; for more, check out
<http://snafu.freedom.org/linux2.2/iproute-notes.html>.
This Quality of Service (QoS) support will enable you to use
Differentiated Services (diffserv) and Resource Reservation Protocol
(RSVP) on your Linux router if you also say Y to "QoS support",
"Packet classifier API" and to some classifiers below. Documentation
and software is at <http://diffserv.sourceforge.net/>.
If you say Y here and to "/proc file system" below, you will be able
to read status information about packet schedulers from the file
/proc/net/psched.
The available schedulers are listed in the following questions; you
can say Y to as many as you like. If unsure, say N now.

---help---
Wide Area Networks (WANs), such as X.25, frame relay and leased
lines, are used to interconnect Local Area Networks (LANs) over vast
distances with data transfer rates significantly higher than those
achievable with commonly used asynchronous modem connections.
Usually, a quite expensive external device called a `WAN router' is
needed to connect to a WAN.
As an alternative, WAN routing can be built into the Linux kernel.
With relatively inexpensive WAN interface cards available on the
market, a perfectly usable router can be built for less than half
the price of an external router. If you have one of those cards and
wish to use your Linux box as a WAN router, say Y here and also to
the WAN driver for your card, below. You will then need the
wan-tools package which is available from <ftp://ftp.sangoma.com/>.
Read <file:Documentation/networking/wan-router.txt> for more
information.
To compile WAN routing support as a module, choose M here: the
module will be called wanrouter.

---help---
X.25 is a set of standardized network protocols, similar in scope to
frame relay; the one physical line from your box to the X.25 network
entry point can carry several logical point-to-point connections
(called "virtual circuits") to other computers connected to the X.25
network. Governments, banks, and other organizations tend to use it
to connect to each other or to form Wide Area Networks (WANs). Many
countries have public X.25 networks. X.25 consists of two
protocols: the higher level Packet Layer Protocol (PLP) (say Y here
if you want that) and the lower level data link layer protocol LAPB
(say Y to "LAPB Data Link Driver" below if you want that).
You can read more about X.25 at <http://www.sangoma.com/x25.htm> and
<http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm>.
Information about X.25 for Linux is contained in the files
<file:Documentation/networking/x25.txt> and
<file:Documentation/networking/x25-iface.txt>.
One connects to an X.25 network either with a dedicated network card
using the X.21 protocol (not yet supported by Linux) or one can do
X.25 over a standard telephone line using an ordinary modem (say Y
to "X.25 async driver" below) or over Ethernet using an ordinary
Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
Driver" and "LAPB over Ethernet driver" below).
