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.

-
- Things remaining to do:
- Better record keeping of errors.
- Eliminate transmit interrupt to reduce overhead.
- Implement "concurrent processing". I won't be doing it!
-
- Bugs:
-
- If you have a problem of not detecting the 82595 during a
- reboot (warm reset), disable the FLASH memory should fix it.
- This is a compatibility hardware problem.
-
- Versions:
- 0.13b basic ethtool support (aris, 09/13/2004)
- 0.13a in memory shortage, drop packets also in board
- (Michael Westermann <mw@microdata-pos.de>, 07/30/2002)
- 0.13 irq sharing, rewrote probe function, fixed a nasty bug in
- hardware_send_packet and a major cleanup (aris, 11/08/2001)
- 0.12d fixing a problem with single card detected as eight eth devices
- fixing a problem with sudden drop in card performance
- (chris (asdn@go2.pl), 10/29/2001)
- 0.12c fixing some problems with old cards (aris, 01/08/2001)
- 0.12b misc fixes (aris, 06/26/2000)
- 0.12a port of version 0.12a of 2.2.x kernels to 2.3.x
- (aris (aris@conectiva.com.br), 05/19/2000)
- 0.11e some tweaks about multiple cards support (PdP, jul/aug 1999)
- 0.11d added __initdata, __init stuff; call spin_lock_init
- in eepro_probe1. Replaced "eepro" by dev->name. Augmented
- the code protected by spin_lock in interrupt routine
- (PdP, 12/12/1998)
- 0.11c minor cleanup (PdP, RMC, 09/12/1998)
- 0.11b Pascal Dupuis (dupuis@lei.ucl.ac.be): works as a module
- under 2.1.xx. Debug messages are flagged as KERN_DEBUG to
- avoid console flooding. Added locking at critical parts. Now
- the dawn thing is SMP safe.
- 0.11a Attempt to get 2.1.xx support up (RMC)
- 0.11 Brian Candler added support for multiple cards. Tested as
- a module, no idea if it works when compiled into kernel.
-
- 0.10e Rick Bressler notified me that ifconfig up;ifconfig down fails
- because the irq is lost somewhere. Fixed that by moving
- request_irq and free_irq to eepro_open and eepro_close respectively.
- 0.10d Ugh! Now Wakeup works. Was seriously broken in my first attempt.
- I'll need to find a way to specify an ioport other than
- the default one in the PnP case. PnP definitively sucks.
- And, yes, this is not the only reason.
- 0.10c PnP Wakeup Test for 595FX. uncomment #define PnPWakeup;
- to use.
- 0.10b Should work now with (some) Pro/10+. At least for
- me (and my two cards) it does. _No_ guarantee for
- function with non-Pro/10+ cards! (don't have any)
- (RMC, 9/11/96)
-
- 0.10 Added support for the Etherexpress Pro/10+. The
- IRQ map was changed significantly from the old
- pro/10. The new interrupt map was provided by
- Rainer M. Canavan (Canavan@Zeus.cs.bonn.edu).
- (BCH, 9/3/96)
-
- 0.09 Fixed a race condition in the transmit algorithm,
- which causes crashes under heavy load with fast
- pentium computers. The performance should also
- improve a bit. The size of RX buffer, and hence
- TX buffer, can also be changed via lilo or insmod.
- (BCH, 7/31/96)
-
- 0.08 Implement 32-bit I/O for the 82595TX and 82595FX
- based lan cards. Disable full-duplex mode if TPE
- is not used. (BCH, 4/8/96)
-
- 0.07a Fix a stat report which counts every packet as a
- heart-beat failure. (BCH, 6/3/95)
-
- 0.07 Modified to support all other 82595-based lan cards.
- The IRQ vector of the EtherExpress Pro will be set
- according to the value saved in the EEPROM. For other
- cards, I will do autoirq_request() to grab the next
- available interrupt vector. (BCH, 3/17/95)
-
- 0.06a,b Interim released. Minor changes in the comments and
- print out format. (BCH, 3/9/95 and 3/14/95)
-
- 0.06 First stable release that I am comfortable with. (BCH,
- 3/2/95)
-
- 0.05 Complete testing of multicast. (BCH, 2/23/95)
-
- 0.04 Adding multicast support. (BCH, 2/14/95)
-
- 0.03 First widely alpha release for public testing.
- (BCH, 2/14/95)

- Sources:
-
- This driver wouldn't have been written without the availability
- of the Crynwr's Lan595 driver source code. It helps me to
- familiarize with the 82595 chipset while waiting for the Intel

-
- This driver is written by cutting and pasting the skeleton.c driver
- provided by Donald Becker. I also borrowed the EEPROM routine from
- Donald Becker's 82586 driver.

- Datasheet for the Intel 82595 (including the TX and FX version). It

- The User Manual for the 82595. It provides a lot of the missing

- Details of the i82595.
-
-You will need either the datasheet or the user manual to understand what
-is going on here. The 82595 is very different from the 82586, 82593.
-
-The receive algorithm in eepro_rx() is just an implementation of the
-RCV ring structure that the Intel 82595 imposes at the hardware level.
-The receive buffer is set at 24K, and the transmit buffer is 8K. I
-am assuming that the total buffer memory is 32K, which is true for the
-Intel EtherExpress Pro/10. If it is less than that on a generic card,
-the driver will be broken.
-
-The transmit algorithm in the hardware_send_packet() is similar to the
-one in the eepro_rx(). The transmit buffer is a ring linked list.
-I just queue the next available packet to the end of the list. In my
-system, the 82595 is so fast that the list seems to always contain a
-single packet. In other systems with faster computers and more congested
-network traffics, the ring linked list should improve performance by
-allowing up to 8K worth of packets to be queued.
-
-The sizes of the receive and transmit buffers can now be changed via lilo
-or insmod. Lilo uses the appended line "ether=io,irq,debug,rx-buffer,eth0"
-where rx-buffer is in KB unit. Modules uses the parameter mem which is
-also in KB unit, for example "insmod io=io-address irq=0 mem=rx-buffer."
-The receive buffer has to be more than 3K or less than 29K. Otherwise,
-it is reset to the default of 24K, and, hence, 8K for the trasnmit
-buffer (transmit-buffer = 32K - receive-buffer).
