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.

-/**
- * DOC: Traps for the unwary
- *
- *	The diagram (Figure 1-1) and the POS summary disagree with the
- *	"Interrupt Level" section in the manual.
- *
- *	The manual contradicts itself when describing the minimum number
- *	buffers in the 'configure lists' command.
- *	My card accepts a buffer config of 4/4.
- *
- *	Setting the SAV BP bit does not save bad packets, but
- *	only enables RX on-card stats collection.
- *
- *	The documentation in places seems to miss things. In actual fact
- *	I've always eventually found everything is documented, it just
- *	requires careful study.
- *
- * DOC: Theory Of Operation
- *
- *	The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- *	amount of on board intelligence that housekeeps a somewhat dumber
- *	Intel NIC. For performance we want to keep the transmit queue deep
- *	as the card can transmit packets while fetching others from main
- *	memory by bus master DMA. Transmission and reception are driven by
- *	circular buffer queues.
- *
- *	The mailboxes can be used for controlling how the card traverses
- *	its buffer rings, but are used only for initial setup in this
- *	implementation.  The exec mailbox allows a variety of commands to
- *	be executed. Each command must complete before the next is
- *	executed. Primarily we use the exec mailbox for controlling the
- *	multicast lists.  We have to do a certain amount of interesting
- *	hoop jumping as the multicast list changes can occur in interrupt
- *	state when the card has an exec command pending. We defer such
- *	events until the command completion interrupt.
- *
- *	A copy break scheme (taken from 3c59x.c) is employed whereby
- *	received frames exceeding a configurable length are passed
- *	directly to the higher networking layers without incuring a copy,
- *	in what amounts to a time/space trade-off.
- *
- *	The card also keeps a large amount of statistical information
- *	on-board. In a perfect world, these could be used safely at no
- *	cost. However, lacking information to the contrary, processing
- *	them without races would involve so much extra complexity as to
- *	make it unworthwhile to do so. In the end, a hybrid SW/HW
- *	implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- *	It should be possible to use two or more cards, but at this stage
- *	only by loading two copies of the same module.
- *
- *	The on-board 82586 NIC has trouble receiving multiple
- *	back-to-back frames and so is likely to drop packets from fast
- *	senders.

- *
- *
- *	An interrupt is raised whenever the 3c527 writes to the command
- *	register. This register contains the message it wishes to send us
- *	packed into a single byte field. We keep reading status entries
- *	until we have processed all the control items, but simply count
- *	transmit and receive reports. When all reports are in we empty the
- *	transceiver rings as appropriate. This saves the overhead of
- *	multiple command requests.
- *
- *	Because MCA is level-triggered, we shouldn't miss indications.
- *	Therefore, we needn't ask the card to suspend interrupts within
- *	this handler. The card receives an implicit acknowledgment of the
- *	current interrupt when we read the command register.
