-/* eth16i.c An ICL EtherTeam 16i and 32 EISA ethernet driver for Linux
-
- Written 1994-1999 by Mika Kuoppala
-
- Copyright (C) 1994-1999 by Mika Kuoppala
- Based on skeleton.c and heavily on at1700.c by Donald Becker
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as miku@iki.fi
-
- This driver supports following cards :
- - ICL EtherTeam 16i
- - ICL EtherTeam 32 EISA
- (Uses true 32 bit transfers rather than 16i compatibility mode)
-
- Example Module usage:
- insmod eth16i.o io=0x2a0 mediatype=bnc
-
- mediatype can be one of the following: bnc,tp,dix,auto,eprom
-
- 'auto' will try to autoprobe mediatype.
- 'eprom' will use whatever type defined in eprom.
-
- I have benchmarked driver with PII/300Mhz as a ftp client
- and 486/33Mhz as a ftp server. Top speed was 1128.37 kilobytes/sec.

- Revision history:
-
- Version Date Description
-
- 0.01 15.12-94 Initial version (card detection)
- 0.02 23.01-95 Interrupt is now hooked correctly
- 0.03 01.02-95 Rewrote initialization part
- 0.04 07.02-95 Base skeleton done...
- Made a few changes to signature checking
- to make it a bit reliable.
- - fixed bug in tx_buf mapping
- - fixed bug in initialization (DLC_EN
- wasn't enabled when initialization
- was done.)
- 0.05 08.02-95 If there were more than one packet to send,
- transmit was jammed due to invalid
- register write...now fixed
- 0.06 19.02-95 Rewrote interrupt handling
- 0.07 13.04-95 Wrote EEPROM read routines
- Card configuration now set according to
- data read from EEPROM
- 0.08 23.06-95 Wrote part that tries to probe used interface
- port if AUTO is selected
-
- 0.09 01.09-95 Added module support
-
- 0.10 04.09-95 Fixed receive packet allocation to work
- with kernels > 1.3.x
-
- 0.20 20.09-95 Added support for EtherTeam32 EISA
-
- 0.21 17.10-95 Removed the unnecessary extern
- init_etherdev() declaration. Some
- other cleanups.
-
- 0.22 22.02-96 Receive buffer was not flushed
- correctly when faulty packet was
- received. Now fixed.
-
- 0.23 26.02-96 Made resetting the adapter
- more reliable.
-
- 0.24 27.02-96 Rewrote faulty packet handling in eth16i_rx
-
- 0.25 22.05-96 kfree() was missing from cleanup_module.
-
- 0.26 11.06-96 Sometimes card was not found by
- check_signature(). Now made more reliable.
-
- 0.27 23.06-96 Oops. 16 consecutive collisions halted
- adapter. Now will try to retransmit
- MAX_COL_16 times before finally giving up.
-
- 0.28 28.10-97 Added dev_id parameter (NULL) for free_irq
-
- 0.29 29.10-97 Multiple card support for module users
-
- 0.30 30.10-97 Fixed irq allocation bug.
- (request_irq moved from probe to open)
-
- 0.30a 21.08-98 Card detection made more relaxed. Driver
- had problems with some TCP/IP-PROM boots
- to find the card. Suggested by
- Kurt Huwig <kurt@huwig.de>
-
- 0.31 28.08-98 Media interface port can now be selected
- with module parameters or kernel
- boot parameters.
-
- 0.32 31.08-98 IRQ was never freed if open/close
- pair wasn't called. Now fixed.
-
- 0.33 10.09-98 When eth16i_open() was called after
- eth16i_close() chip never recovered.
- Now more shallow reset is made on
- close.
-
- 0.34 29.06-99 Fixed one bad #ifdef.
- Changed ioaddr -> io for consistency
-
- 0.35 01.07-99 transmit,-receive bytes were never
- updated in stats.
-
- Bugs:
- In some cases the media interface autoprobing code doesn't find
- the correct interface type. In this case you can
- manually choose the interface type in DOS with E16IC.EXE which is
- configuration software for EtherTeam16i and EtherTeam32 cards.
- This is also true for IRQ setting. You cannot use module
- parameter to configure IRQ of the card (yet).
-
- To do:
- - Real multicast support
- - Rewrite the media interface autoprobing code. Its _horrible_ !
- - Possibly merge all the MB86965 specific code to external
- module for use by eth16.c and Donald's at1700.c
- - IRQ configuration with module parameter. I will do
- this when i will get enough info about setting
- irq without configuration utility.
