Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

14 Things remaining to do:
15 Better record keeping of errors.
16 Eliminate transmit interrupt to reduce overhead.
17 Implement "concurrent processing". I won't be doing it!
18
19 Bugs:
20
21 If you have a problem of not detecting the 82595 during a
22 reboot (warm reset), disable the FLASH memory should fix it.
23 This is a compatibility hardware problem.
24
25 Versions:
26 0.13b basic ethtool support (aris, 09/13/2004)
27 0.13a in memory shortage, drop packets also in board
28 (Michael Westermann <mw@microdata-pos.de>, 07/30/2002)
29 0.13 irq sharing, rewrote probe function, fixed a nasty bug in
30 hardware_send_packet and a major cleanup (aris, 11/08/2001)
31 0.12d fixing a problem with single card detected as eight eth devices
32 fixing a problem with sudden drop in card performance
33 (chris (asdn@go2.pl), 10/29/2001)
34 0.12c fixing some problems with old cards (aris, 01/08/2001)
35 0.12b misc fixes (aris, 06/26/2000)
36 0.12a port of version 0.12a of 2.2.x kernels to 2.3.x
37 (aris (aris@conectiva.com.br), 05/19/2000)
38 0.11e some tweaks about multiple cards support (PdP, jul/aug 1999)
39 0.11d added __initdata, __init stuff; call spin_lock_init
40 in eepro_probe1. Replaced "eepro" by dev->name. Augmented
41 the code protected by spin_lock in interrupt routine
42 (PdP, 12/12/1998)
43 0.11c minor cleanup (PdP, RMC, 09/12/1998)
44 0.11b Pascal Dupuis (dupuis@lei.ucl.ac.be): works as a module
45 under 2.1.xx. Debug messages are flagged as KERN_DEBUG to
46 avoid console flooding. Added locking at critical parts. Now
47 the dawn thing is SMP safe.
48 0.11a Attempt to get 2.1.xx support up (RMC)
49 0.11 Brian Candler added support for multiple cards. Tested as
50 a module, no idea if it works when compiled into kernel.
51
52 0.10e Rick Bressler notified me that ifconfig up;ifconfig down fails
53 because the irq is lost somewhere. Fixed that by moving
54 request_irq and free_irq to eepro_open and eepro_close respectively.
55 0.10d Ugh! Now Wakeup works. Was seriously broken in my first attempt.
56 I'll need to find a way to specify an ioport other than
57 the default one in the PnP case. PnP definitively sucks.
58 And, yes, this is not the only reason.
59 0.10c PnP Wakeup Test for 595FX. uncomment #define PnPWakeup;
60 to use.
61 0.10b Should work now with (some) Pro/10+. At least for
62 me (and my two cards) it does. _No_ guarantee for
63 function with non-Pro/10+ cards! (don't have any)
64 (RMC, 9/11/96)
65
66 0.10 Added support for the Etherexpress Pro/10+. The
67 IRQ map was changed significantly from the old
68 pro/10. The new interrupt map was provided by
69 Rainer M. Canavan (Canavan@Zeus.cs.bonn.edu).
70 (BCH, 9/3/96)
71
72 0.09 Fixed a race condition in the transmit algorithm,
73 which causes crashes under heavy load with fast
74 pentium computers. The performance should also
75 improve a bit. The size of RX buffer, and hence
76 TX buffer, can also be changed via lilo or insmod.
77 (BCH, 7/31/96)
78
79 0.08 Implement 32-bit I/O for the 82595TX and 82595FX
80 based lan cards. Disable full-duplex mode if TPE
81 is not used. (BCH, 4/8/96)
82
83 0.07a Fix a stat report which counts every packet as a
84 heart-beat failure. (BCH, 6/3/95)
85
86 0.07 Modified to support all other 82595-based lan cards.
87 The IRQ vector of the EtherExpress Pro will be set
88 according to the value saved in the EEPROM. For other
89 cards, I will do autoirq_request() to grab the next
90 available interrupt vector. (BCH, 3/17/95)
91
92 0.06a,b Interim released. Minor changes in the comments and
93 print out format. (BCH, 3/9/95 and 3/14/95)
94
95 0.06 First stable release that I am comfortable with. (BCH,
96 3/2/95)
97
98 0.05 Complete testing of multicast. (BCH, 2/23/95)
99
100 0.04 Adding multicast support. (BCH, 2/14/95)
101
102 0.03 First widely alpha release for public testing.

115 This driver wouldn't have been written without the availability
116 of the Crynwr's Lan595 driver source code. It helps me to
117 familiarize with the 82595 chipset while waiting for the Intel
118 documentation. I also learned how to detect the 82595 using
119 the packet driver's technique.
120
121 This driver is written by cutting and pasting the skeleton.c driver
122 provided by Donald Becker. I also borrowed the EEPROM routine from
123 Donald Becker's 82586 driver.

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

327 Details of the i82595.
328
329You will need either the datasheet or the user manual to understand what
330is going on here. The 82595 is very different from the 82586, 82593.
331
332The receive algorithm in eepro_rx() is just an implementation of the
333RCV ring structure that the Intel 82595 imposes at the hardware level.
334The receive buffer is set at 24K, and the transmit buffer is 8K. I
335am assuming that the total buffer memory is 32K, which is true for the
336Intel EtherExpress Pro/10. If it is less than that on a generic card,
337the driver will be broken.
338
339The transmit algorithm in the hardware_send_packet() is similar to the
340one in the eepro_rx(). The transmit buffer is a ring linked list.
341I just queue the next available packet to the end of the list. In my
342system, the 82595 is so fast that the list seems to always contain a
343single packet. In other systems with faster computers and more congested
344network traffics, the ring linked list should improve performance by
345allowing up to 8K worth of packets to be queued.
346
347The sizes of the receive and transmit buffers can now be changed via lilo
348or insmod. Lilo uses the appended line "ether=io,irq,debug,rx-buffer,eth0"
349where rx-buffer is in KB unit. Modules uses the parameter mem which is
350also in KB unit, for example "insmod io=io-address irq=0 mem=rx-buffer."
351The receive buffer has to be more than 3K or less than 29K. Otherwise,
352it is reset to the default of 24K, and, hence, 8K for the trasnmit
353buffer (transmit-buffer = 32K - receive-buffer).
