The new Networking menu looks unstructured.
And the net/Kconfig file contains a lot of config snippets that does not
belong there.
So I took a stamp on it with focus on:
- Move config bits to appropriate places, creating several new Kconfig
  files
- Made uses of menus more consistent at least on first and second level
- Move submenu to the top
- Rename top menu to "Networking" and located it just before
 "File systems"


The patch became much larger. The win is that the top-level
net/Kconfig contains much less cruft.

Many of the 56 lines added are due to the additional files.
I did not (on purpose) change any functionality.

Only bit that I am worried about is the statement in SCTP:
        depends on IPV6 || IPV6=n

That looked like a noop to me. It had the sideeffect that SCTP
menu entries where idented an extra level which was not desireable
with currect layout.

Comments appreciated.

Patch on top of rc2.

package
-         so that your Linux box can act as a print and file server for Macs as

-         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).

-
-         One connects to an X.25 network either with a dedicated network card

-         achievable with commonly used asynchronous modem connections.
-         Usually, a quite expensive external device called a `WAN router' is

-
-         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

-         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

-
-         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

-         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/>.
