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.

-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,

-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

-
-# modprobe sktr
-
-This will produce output similar to the following: (Output is user specific)

- * Technical Card Details
- *
- * All access to data is done with 16/8 bit transfers. The transfer
- * method really sucks. You can only read or write one location at a time.
- *
- * Also, the microcode for the card must be uploaded if the card does not have
- * the flashrom on board. This is a 28K bloat in the driver when compiled
- * as a module.
- *
- * Rx is very simple, status into a ring of descriptors, dma data transfer,
- * interrupts to tell us when a packet is received.
- *
- * Tx is a little more interesting. Similar scenario, descriptor and dma data
- * transfers, but we don't have to interrupt the card to tell it another packet
- * is ready for transmission, we are just doing simple memory writes, not io or mmio
- * writes. The card can be set up to simply poll on the next
- * descriptor pointer and when this value is non-zero will automatically download
- * the next packet. The card then interrupts us when the packet is done.

- * There are two ways of implementing rx on the 359 NIC, either

- * entries point to the next entry except for the last entry in the ring
- * which points to 0. The card is programmed with the location of the first
- * available descriptor and keeps reading the next_ptr until next_ptr is set
- * to 0. Hopefully with a ring size of 16 the card will never get to read a next_ptr
- * of 0. As the Rx interrupt is received we copy the frame up to the protocol layers
- * and then point the end of the ring to our current position and point our current
- * position to 0, therefore making the current position the last position on the ring.
- * The last position on the ring therefore loops continually loops around the rx ring.
- *
- * rx_ring_tail is the position on the ring to process next. (Think of a snake, the head
- * expands as the card adds new packets and we go around eating the tail processing the
- * packets.)
- *
- * Undoubtably it could be streamlined and improved upon, but at the moment it works
