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.

- * Linux Ethernet device driver for the 3Com Etherlink Plus (3C505)
- *      By Craig Southeren, Juha Laiho and Philip Blundell
- *
- * 3c505.c      This module implements an interface to the 3Com
- *              Etherlink Plus (3c505) Ethernet card. Linux device
- *              driver interface reverse engineered from the Linux 3C509
- *              device drivers. Some 3C505 information gleaned from
- *              the Crynwr packet driver. Still this driver would not
- *              be here without 3C505 technical reference provided by
- *              3Com.

-/* Theory of operation:
- *
- * The 3c505 is quite an intelligent board.  All communication with it is done
- * by means of Primary Command Blocks (PCBs); these are transferred using PIO
- * through the command register.  The card has 256k of on-board RAM, which is
- * used to buffer received packets.  It might seem at first that more buffers
- * are better, but in fact this isn't true.  From my tests, it seems that
- * more than about 10 buffers are unnecessary, and there is a noticeable
- * performance hit in having more active on the card.  So the majority of the
- * card's memory isn't, in fact, used.  Sadly, the card only has one transmit
- * buffer and, short of loading our own firmware into it (which is what some
- * drivers resort to) there's nothing we can do about this.
- *
- * We keep up to 4 "receive packet" commands active on the board at a time.
- * When a packet comes in, so long as there is a receive command active, the
- * board will send us a "packet received" PCB and then add the data for that
- * packet to the DMA queue.  If a DMA transfer is not already in progress, we
- * set one up to start uploading the data.  We have to maintain a list of
- * backlogged receive packets, because the card may decide to tell us about
- * a newly-arrived packet at any time, and we may not be able to start a DMA
- * transfer immediately (ie one may already be going on).  We can't NAK the
- * PCB, because then it would throw the packet away.
- *
- * Trying to send a PCB to the card at the wrong moment seems to have bad
- * effects.  If we send it a transmit PCB while a receive DMA is happening,
- * it will just NAK the PCB and so we will have wasted our time.  Worse, it
- * sometimes seems to interrupt the transfer.  The majority of the low-level
- * code is protected by one huge semaphore -- "busy" -- which is set whenever
- * it probably isn't safe to do anything to the card.  The receive routine
- * must gain a lock on "busy" before it can start a DMA transfer, and the
- * transmit routine must gain a lock before it sends the first PCB to the card.
- * The send_pcb() routine also has an internal semaphore to protect it against
- * being re-entered (which would be disastrous) -- this is needed because
- * several things can happen asynchronously (re-priming the receiver and
- * asking the card for statistics, for example).  send_pcb() will also refuse
- * to talk to the card at all if a DMA upload is happening.  The higher-level
- * networking code will reschedule a later retry if some part of the driver
- * is blocked.  In practice, this doesn't seem to happen very often.
- */
-
-/* This driver may now work with revision 2.x hardware, since all the read
- * operations on the HCR have been removed (we now keep our own softcopy).
- * But I don't have an old card to test it on.
- *
- * This has had the bad effect that the autoprobe routine is now a bit
- * less friendly to other devices.  However, it was never very good.
- * before, so I doubt it will hurt anybody.
- */
-
-/* The driver is a mess.  I took Craig's and Juha's code, and hacked it firstly
- * to make it more reliable, and secondly to add DMA mode.  Many things could
- * probably be done better; the concurrency protection is particularly awful.
