This driver supports following cards :
- ICL EtherTeam 16i
- - ICL EtherTeam 32 EISA
+ - ICL EtherTeam 32 EISA
+ (Uses true 32 bit transfers rather than 16i compability mode)
+
+ Example Module usage:
+ insmod eth16i.o ioaddr=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.

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

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
+ 0.09 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)
- 0.21a 15.08-97 Made signature check less restrictive to
- detect card that have been used for booting
- with a bootprom.
+ 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.
+
Bugs:
- In some cases the interface autoprobing code doesn't find
+ 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.
