tokenring: delete all remaining driver support 

This represents the mass deletion of the of the tokenring support.

It gets rid of:
  - the net/tr.c which the drivers depended on
  - the drivers/net component
  - the Kbuild infrastructure around it
  - any tokenring related CONFIG_ settings in any defconfigs
  - the tokenring headers in the include/linux dir
  - the firmware associated with the tokenring drivers.
  - any associated token ring documentation.

3COM PCI TOKEN LINK VELOCITY XL TOKEN RING CARDS README
Release 0.9.0 - Release
Jul 17th 2000 Mike Phillips
1.2.0 - Final
Feb 17th 2002 Mike Phillips
Updated for submission to the 2.4.x kernel.
Thanks:
Terry Murphy from 3Com for tech docs and support,
Adam D. Ligas for testing the driver.
Note:
This driver will NOT work with the 3C339 Token Ring cards, you need
to use the tms380 driver instead.
Options:
The driver accepts three options: ringspeed, pkt_buf_sz and message_level.
These options can be specified differently for each card found.
ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
make the card autosense the ringspeed and join at the appropriate speed,
this will be the default option for most people. 4 or 16 allow you to
explicitly force the card to operate at a certain speed. The card will fail
if you try to insert it at the wrong speed. (Although some hubs will allow
this so be *very* careful). The main purpose for explicitly setting the ring
speed is for when the card is first on the ring. In autosense mode, if the card
cannot detect any active monitors on the ring it will open at the same speed as
its last opening. This can be hazardous if this speed does not match the speed
you want the ring to operate at.
pkt_buf_sz: This is this initial receive buffer allocation size. This will
default to 4096 if no value is entered. You may increase performance of the
driver by setting this to a value larger than the network packet size, although
the driver now re-sizes buffers based on MTU settings as well.
message_level: Controls level of messages created by the driver. Defaults to 0:
which only displays start-up and critical messages. Presently any non-zero
value will display all soft messages as well. NB This does not turn
debugging messages on, that must be done by modified the source code.
Variable MTU size:
The driver can handle a MTU size up to either 4500 or 18000 depending upon
ring speed. The driver also changes the size of the receive buffers as part
of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
position = 296,000 bytes of memory space, plus of course anything
necessary for the tx sk_buff's. Remember this is per card, so if you are
building routers, gateway's etc, you could start to use a lot of memory
real fast.

IBM PCI Pit/Pit-Phy/Olympic CHIPSET BASED TOKEN RING CARDS README
Release 0.2.0 - Release
June 8th 1999 Peter De Schrijver & Mike Phillips
Release 0.9.C - Release
April 18th 2001 Mike Phillips
Thanks:
Erik De Cock, Adrian Bridgett and Frank Fiene for their
patience and testing.
Donald Champion for the cardbus support
Kyle Lucke for the dma api changes.
Jonathon Bitner for hardware support.
Everybody on linux-tr for their continued support.
Options:
The driver accepts four options: ringspeed, pkt_buf_sz,
message_level and network_monitor.
These options can be specified differently for each card found.
ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
make the card autosense the ringspeed and join at the appropriate speed,
this will be the default option for most people. 4 or 16 allow you to
explicitly force the card to operate at a certain speed. The card will fail
if you try to insert it at the wrong speed. (Although some hubs will allow
this so be *very* careful). The main purpose for explicitly setting the ring
speed is for when the card is first on the ring. In autosense mode, if the card
cannot detect any active monitors on the ring it will not open, so you must
re-init the card at the appropriate speed. Unfortunately at present the only
way of doing this is rmmod and insmod which is a bit tough if it is compiled
in the kernel.
pkt_buf_sz: This is this initial receive buffer allocation size. This will
default to 4096 if no value is entered. You may increase performance of the
driver by setting this to a value larger than the network packet size, although
the driver now re-sizes buffers based on MTU settings as well.
message_level: Controls level of messages created by the driver. Defaults to 0:
which only displays start-up and critical messages. Presently any non-zero
value will display all soft messages as well. NB This does not turn
debugging messages on, that must be done by modified the source code.
network_monitor: Any non-zero value will provide a quasi network monitoring
mode. All unexpected MAC frames (beaconing etc.) will be received
by the driver and the source and destination addresses printed.
Also an entry will be added in /proc/net called olympic_tr%d, where tr%d
is the registered device name, i.e tr0, tr1, etc. This displays low
level information about the configuration of the ring and the adapter.
This feature has been designed for network administrators to assist in
the diagnosis of network / ring problems. (This used to OLYMPIC_NETWORK_MONITOR,
but has now changed to allow each adapter to be configured differently and
to alleviate the necessity to re-compile olympic to turn the option on).
Multi-card:
The driver will detect multiple cards and will work with shared interrupts,
each card is assigned the next token ring device, i.e. tr0 , tr1, tr2. The
driver should also happily reside in the system with other drivers. It has
been tested with ibmtr.c running, and I personally have had one Olicom PCI
card and two IBM olympic cards (all on the same interrupt), all running
together.
Variable MTU size:
The driver can handle a MTU size up to either 4500 or 18000 depending upon
ring speed. The driver also changes the size of the receive buffers as part
of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
position = 296,000 bytes of memory space, plus of course anything
necessary for the tx sk_buff's. Remember this is per card, so if you are

Text File for the SMC TokenCard TokenRing Linux driver (smctr.c).
By Jay Schulist <jschlst@samba.org>
The Linux SMC Token Ring driver works with the SMC TokenCard Elite (8115T)
ISA and SMC TokenCard Elite/A (8115T/A) MCA adapters.
Latest information on this driver can be obtained on the Linux-SNA WWW site.
Please point your browser to: http://www.linux-sna.org
This driver is rather simple to use. Select Y to Token Ring adapter support
in the kernel configuration. A choice for SMC Token Ring adapters will
appear. This drives supports all SMC ISA/MCA adapters. Choose this
option. I personally recommend compiling the driver as a module (M), but if you
you would like to compile it statically answer Y instead.
This driver supports multiple adapters without the need to load multiple copies
of the driver. You should be able to load up to 7 adapters without any kernel
modifications, if you are in need of more please contact the maintainer of this
driver.
Load the driver either by lilo/loadlin or as a module. When a module using the
following command will suffice for most:
# modprobe smctr
smctr.c: v1.00 12/6/99 by jschlst@samba.org
tr0: SMC TokenCard 8115T at Io 0x300, Irq 10, Rom 0xd8000, Ram 0xcc000.
Now just setup the device via ifconfig and set and routes you may have. After
this you are ready to start sending some tokens.
Errata:
1). For anyone wondering where to pick up the SMC adapters please browse
to http://www.smc.com
2). If you are the first/only Token Ring Client on a Token Ring LAN, please
specify the ringspeed with the ringspeed=[4/16] module option. If no
ringspeed is specified the driver will attempt to autodetect the ring
speed and/or if the adapter is the first/only station on the ring take
the appropriate actions.
NOTE: Default ring speed is 16MB UTP.
3). PnP support for this adapter sucks. I recommend hard setting the
IO/MEM/IRQ by the jumpers on the adapter. If this is not possible
load the module with the following io=[ioaddr] mem=[mem_addr]
irq=[irq_num].
The following IRQ, IO, and MEM settings are supported.
IO ports:
0x200, 0x220, 0x240, 0x260, 0x280, 0x2A0, 0x2C0, 0x2E0, 0x300,
0x320, 0x340, 0x360, 0x380.
IRQs:
2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15
Memory addresses:
0xA0000, 0xA4000, 0xA8000, 0xAC000, 0xB0000, 0xB4000,
0xB8000, 0xBC000, 0xC0000, 0xC4000, 0xC8000, 0xCC000,
0xD0000, 0xD4000, 0xD8000, 0xDC000, 0xE0000, 0xE4000,
0xE8000, 0xEC000, 0xF0000, 0xF4000, 0xF8000, 0xFC000

included as an initialized C-array and is licensed by SMC to the Linux
users of this driver. However no warranty about its fitness is expressed or
implied by SMC.

Text file for the Linux SysKonnect Token Ring ISA/PCI Adapter Driver.
Text file by: Jay Schulist <jschlst@samba.org>
The Linux SysKonnect Token Ring driver works with the SysKonnect TR4/16(+) ISA,
SysKonnect TR4/16(+) PCI, SysKonnect TR4/16 PCI, and older revisions of the
SK NET TR4/16 ISA card.
Latest information on this driver can be obtained on the Linux-SNA WWW site.
Please point your browser to:
http://www.linux-sna.org
Many thanks to Christoph Goos for his excellent work on this driver and
SysKonnect for donating the adapters to Linux-SNA for the testing and
maintenance of this device driver.
Important information to be noted:
1. Adapters can be slow to open (~20 secs) and close (~5 secs), please be
patient.
2. This driver works very well when autoprobing for adapters. Why even
think about those nasty io/int/dma settings of modprobe when the driver
will do it all for you!
This driver is rather simple to use. Select Y to Token Ring adapter support
in the kernel configuration. A choice for SysKonnect Token Ring adapters will
appear. This drives supports all SysKonnect ISA and PCI adapters. Choose this
option. I personally recommend compiling the driver as a module (M), but if you
you would like to compile it statically answer Y instead.
This driver supports multiple adapters without the need to load multiple copies
of the driver. You should be able to load up to 7 adapters without any kernel
modifications, if you are in need of more please contact the maintainer of this
driver.
Load the driver either by lilo/loadlin or as a module. When a module using the
following command will suffice for most:
# modprobe sktr
This will produce output similar to the following: (Output is user specific)
sktr.c: v1.01 08/29/97 by Christoph Goos
tr0: SK NET TR 4/16 PCI found at 0x6100, using IRQ 17.
tr1: SK NET TR 4/16 PCI found at 0x6200, using IRQ 16.
tr2: SK NET TR 4/16 ISA found at 0xa20, using IRQ 10 and DMA 5.
Now just setup the device via ifconfig and set and routes you may have. After
this you are ready to start sending some tokens.

help
Token Ring is IBM's way of communication on a local network; the
rest of the world uses Ethernet. To participate on a Token Ring
network, you need a special Token ring network card. If you are
connected to such a Token Ring network and want to use your Token
Ring card under Linux, say Y here and to the driver for your
particular card below and read the Token-Ring mini-HOWTO, available
from <http://www.tldp.org/docs.html#howto>. Most people can
say N here.

/*======================================================================
A PCMCIA token-ring driver for IBM-based cards
This driver supports the IBM PCMCIA Token-Ring Card.
Written by Steve Kipisz, kipisz@vnet.ibm.com or
bungy@ibm.net
Written 1995,1996.
This code is based on pcnet_cs.c from David Hinds.
V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
Linux V2.2.x presented significant changes to the underlying
ibmtr.c code. Mainly the code became a lot more organized and
modular.
This caused the old PCMCIA Token Ring driver to give up and go
home early. Instead of just patching the old code to make it
work, the PCMCIA code has been streamlined, updated and possibly
improved.
This code now only contains code required for the Card Services.
All we do here is set the card up enough so that the real ibmtr.c
driver can find it and work with it properly.
i.e. We set up the io port, irq, mmio memory and shared ram
memory. This enables ibmtr_probe in ibmtr.c to find the card and
configure it as though it was a normal ISA and/or PnP card.
CHANGES
v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
Updated to version 2.2.7 to match the first version of the kernel
that the modification to ibmtr.c were incorporated into.
v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
Address translation feature of PCMCIA controller is usable so
memory windows can be placed in High memory (meaning above
0xFFFFF.)

/*
* Handle interrupts generated by the card
*
* The MicroChannel Madge cards need slightly more handling
* after an interrupt than other TMS380 cards do.
*
* First we must make sure it was this card that generated the
* interrupt (since interrupt sharing is allowed). Then,
* because we're using level-triggered interrupts (as is
* standard on MCA), we must toggle the interrupt line
* on the card in order to claim and acknowledge the interrupt.
* Once that is done, the interrupt should be handlable in
* the normal tms380tr_interrupt() routine.
*
* There's two ways we can check to see if the interrupt is ours,
* both with their own disadvantages...
*
* 1) Read in the SIFSTS register from the TMS controller. This
* is guaranteed to be accurate, however, there's a fairly
* large performance penalty for doing so: the Madge chips
* must request the register from the Eagle, the Eagle must
* read them from its internal bus, and then take the route
* back out again, for a 16bit read.
*
* 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
* The major disadvantage here is that the accuracy of the
* bit is in question. However, it cuts out the extra read
* cycles it takes to read the Eagle's SIF, as its only an
* 8bit read, and theoretically the Madge bit is directly
* connected to the interrupt latch coming out of the Eagle
* hardware (that statement is not verified).
*
* I can't determine which of these methods has the best win. For now,
* we make a compromise. Use the Madge way for the first interrupt,
* which should be the fast-path, and then once we hit the first
* interrupt, keep on trying using the SIF method until we've
* exhausted all contiguous interrupts.
