i825xx: Move the Intel 82586/82593/82596 based drivers
Move the drivers that use the i82586/i82593/i82596 chipsets into drivers/net/ethernet/i825xx/ and make the necessary Kconfig and Makefile changes. There were 4 3Com drivers which were initially moved into 3com/, which now reside in i825xx since they all used the i82586 chip.

-/* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
- munged into HPPA boxen .
-
- This driver is based upon 82596.c, original credits are below...
- but there were too many hoops which HP wants jumped through to
- keep this code in there in a sane manner.
-
- 3 primary sources of the mess --
- 1) hppa needs *lots* of cacheline flushing to keep this kind of
- MMIO running.
-
- 2) The 82596 needs to see all of its pointers as their physical
- address. Thus virt_to_bus/bus_to_virt are *everywhere*.
-
- 3) The implementation HP is using seems to be significantly pickier
- about when and how the command and RX units are started. some
- command ordering was changed.
-
- Examination of the mach driver leads one to believe that there
- might be a saner way to pull this off... anyone who feels like a
- full rewrite can be my guest.

- Split 02/13/2000 Sam Creasey (sammy@oh.verio.com)
-
- 02/01/2000 Initial modifications for parisc by Helge Deller (deller@gmx.de)
- 03/02/2000 changes for better/correct(?) cache-flushing (deller)

-/* 82596.c: A generic 82596 ethernet driver for linux. */
-/*
- Based on Apricot.c
- Written 1994 by Mark Evans.
- This driver is for the Apricot 82596 bus-master interface
-
- Modularised 12/94 Mark Evans
-
-
- Modified to support the 82596 ethernet chips on 680x0 VME boards.
- by Richard Hirst <richard@sleepie.demon.co.uk>
- Renamed to be 82596.c
-
- 980825: Changed to receive directly in to sk_buffs which are
- allocated at open() time. Eliminates copy on incoming frames
- (small ones are still copied). Shared data now held in a
- non-cached page, so we can run on 68060 in copyback mode.
-
- TBD:
- * look at deferring rx frames rather than discarding (as per tulip)
- * handle tx ring full as per tulip
- * performance test to tune rx_copybreak
-
- Most of my modifications relate to the braindead big-endian
- implementation by Intel. When the i596 is operating in
- 'big-endian' mode, it thinks a 32 bit value of 0x12345678
- should be stored as 0x56781234. This is a real pain, when
- you have linked lists which are shared by the 680x0 and the
- i596.
