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.
