3c*/acenic/typhoon: Move 3Com Ethernet drivers

Moves the 3Com drivers into drivers/net/ethernet/3com/ and the necessary
Kconfig and Makefile changes.

Did not move the following drivers becuase they use a non-3Com
chipset: 3c503, 3c505, 3c507, 3c523 and 3c527

-/* 3c509.c: A 3c509 EtherLink3 ethernet driver for linux. */

-	Director, National Security Agency.	 This software may be used and

-
-	This driver is for the 3Com EtherLinkIII series.

-
-	Known limitations:
-	Because of the way 3c509 ISA detection works it's difficult to predict
-	a priori which of several ISA-mode cards will be detected first.
-
-	This driver does not use predictive interrupt mode, resulting in higher
-	packet latency but lower overhead.  If interrupts are disabled for an
-	unusually long time it could also result in missed packets, but in
-	practice this rarely happens.
-
-
-	FIXES:
-		Alan Cox:       Removed the 'Unexpected interrupt' bug.
-		Michael Meskes:	Upgraded to Donald Becker's version 1.07.
-		Alan Cox:	Increased the eeprom delay. Regardless of
-				what the docs say some people definitely
-				get problems with lower (but in card spec)
-				delays
-		v1.10 4/21/97 Fixed module code so that multiple cards may be detected,
-				other cleanups.  -djb
-		Andrea Arcangeli:	Upgraded to Donald Becker's version 1.12.
-		Rick Payne:	Fixed SMP race condition
-		v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb
-		v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb
-		v1.15 1/31/98 Faster recovery for Tx errors. -djb
-		v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb
-		v1.18 12Mar2001 Andrew Morton
-			- Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz)
-			- Reviewed against 1.18 from scyld.com
-		v1.18a 17Nov2001 Jeff Garzik <jgarzik@pobox.com>
-			- ethtool support
-		v1.18b 1Mar2002 Zwane Mwaikambo <zwane@commfireservices.com>
-			- Power Management support
-		v1.18c 1Mar2002 David Ruggiero <jdr@farfalle.com>
-			- Full duplex support
-		v1.19  16Oct2002 Zwane Mwaikambo <zwane@linuxpower.ca>
-			- Additional ethtool features
-		v1.19a 28Oct2002 Davud Ruggiero <jdr@farfalle.com>
-			- Increase *read_eeprom udelay to workaround oops with 2 cards.
-		v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org>
-			- Introduce driver model for EISA cards.
-		v1.20  04Feb2008 Ondrej Zary <linux@rainbow-software.org>
-			- convert to isa_driver and pnp_driver and some cleanups
