[NET]: move config options out to individual protocols 



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.

	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

	  If you say Y here, then your Linux box will be able to act as an

	  is connected to will appear as one Ethernet to the participants.

	  Several such bridges can work together to create even larger

	  networks of Ethernets using the IEEE 802.1 spanning tree algorithm.

	  As this is a standard, Linux bridges will cooperate properly with

	  other third party bridge products.



	  In order to use the Ethernet bridge, you'll need the bridge

	  configuration tools; see <file:Documentation/networking/bridge.txt>

	  for location. Please read the Bridge mini-HOWTO for more

	  information.



	  If you enable iptables support along with the bridge support then you

	  turn your bridge into a bridging IP firewall.

	  iptables will then see the IP packets being bridged, so you need to

	  take this into account when setting up your firewall rules.

	  Enabling arptables support when bridging will let arptables see

	  bridged ARP traffic in the arptables FORWARD chain.

	  Be sure to say Y to "/proc file system support" and "Sysctl support"

	  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

	  X.25 is a set of standardized network protocols, similar in scope to

	  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

	  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

	  If you say Y here, then your Linux box will be able to act as an

	  Ethernet bridge, which means that the different Ethernet segments it

	  is connected to will appear as one Ethernet to the participants.

	  Several such bridges can work together to create even larger

	  networks of Ethernets using the IEEE 802.1 spanning tree algorithm.

	  As this is a standard, Linux bridges will cooperate properly with

	  other third party bridge products.



	  In order to use the Ethernet bridge, you'll need the bridge

	  configuration tools; see <file:Documentation/networking/bridge.txt>

	  for location. Please read the Bridge mini-HOWTO for more

	  information.



	  If you enable iptables support along with the bridge support then you

	  turn your bridge into a bridging IP firewall.

	  iptables will then see the IP packets being bridged, so you need to

	  take this into account when setting up your firewall rules.

	  Enabling arptables support when bridging will let arptables see

	  bridged ARP traffic in the arptables FORWARD chain.



	  To compile this code as a module, choose M here: the module

	  will be called bridge.



	  If unsure, say N.
