staging: ipx: delete it from the tree

Browse Source 
The ipx code moved into the staging tree back in November 2017 and no
one has complained or even noticed it was gone.  Because of that, let's
just delete it.

Note, the ipx header files are not removed here, that will come later
through the networking tree, as that takes a bit more work to unwind.

# IPX configuration

config IPX
tristate "The IPX protocol"
depends on NET
select LLC
---help---
This is support for the Novell networking protocol, IPX, commonly
used for local networks of Windows machines. You need it if you
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.
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
information, read the IPX-HOWTO available from
<http://www.tldp.org/docs.html#howto>.
The IPX driver would enlarge your kernel by about 16 KB. To compile
this driver as a module, choose M here: the module will be called ipx.
Unless you want to integrate your Linux box with a local Novell
network, say N.
config IPX_INTERN
bool "IPX: Full internal IPX network"
depends on IPX
---help---
Every IPX network has an address that identifies it. Sometimes it is
useful to give an IPX "network" address to your Linux box as well
(for example if your box is acting as a file server for different
IPX networks: it will then be accessible from everywhere using the
same address). The way this is done is to create a virtual internal
"network" inside your box and to assign an IPX address to this
network. Say Y here if you want to do this; read the IPX-HOWTO at
<http://www.tldp.org/docs.html#howto> for details.
The full internal IPX network enables you to allocate sockets on
different virtual nodes of the internal network. This is done by
evaluating the field sipx_node of the socket address given to the
bind call. So applications should always initialize the node field
to 0 when binding a socket on the primary network. In this case the
socket is assigned the default node that has been given to the
kernel when the internal network was created. By enabling the full
internal IPX network the cross-forwarding of packets targeted at
'special' sockets to sockets listening on the primary network is
disabled. This might break existing applications, especially RIP/SAP
daemons. A RIP/SAP daemon that works well with the full internal net
can be found on <ftp://ftp.gwdg.de/pub/linux/misc/ncpfs/>.
If you don't know what you are doing, say N.

The ipx code will be removed soon from the kernel tree as it is old and
obsolete and broken.
Don't worry about fixing up anything here, it's not needed.
