Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+/* eth16i.c An ICL EtherTeam 16i and 32 EISA ethernet driver for Linux

+
+   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.
+
+   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.
