   This driver supports following cards :
	- ICL EtherTeam 16i
	- ICL EtherTeam 32 EISA
	  (Uses true 32 bit transfers rather than 16i compability 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.

   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.
