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)

/*

|
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).
