-net-3-driver for the IBM LAN Adapter/A
-
-This is an extension to the Linux operating system, and is covered by the
-same GNU General Public License that covers that work.
-
-Copyright 1999 by Alfred Arnold (alfred@ccac.rwth-aachen.de,
- alfred.arnold@lancom.de)
-
-This driver is based both on the SK_MCA driver, which is itself based on the
-SK_G16 and 3C523 driver.
-
-paper sources:
- 'PC Hardware: Aufbau, Funktionsweise, Programmierung' by
- Hans-Peter Messmer for the basic Microchannel stuff
-
- 'Linux Geraetetreiber' by Allesandro Rubini, Kalle Dalheimer
- for help on Ethernet driver programming
-
- 'DP83934CVUL-20/25 MHz SONIC-T Ethernet Controller Datasheet' by National
- Semiconductor for info on the MAC chip
-
- 'LAN Technical Reference Ethernet Adapter Interface Version 1 Release 1.0
- Document Number SC30-3661-00' by IBM for info on the adapter itself
-
- Also see http://www.national.com/analog
-
-special acknowledgements to:
- - Bob Eager for helping me out with documentation from IBM
- - Jim Shorney for his endless patience with me while I was using
- him as a beta tester to trace down the address filter bug ;-)
-
- Missing things:
-
- -> set debug level via ioctl instead of compile-time switches
- -> I didn't follow the development of the 2.1.x kernels, so my
- assumptions about which things changed with which kernel version
- are probably nonsense
-
-History:
- Nov 6th, 1999
- startup from SK_MCA driver
- Dec 6th, 1999
- finally got docs about the card. A big thank you to Bob Eager!
- Dec 12th, 1999
- first packet received
- Dec 13th, 1999
- recv queue done, tcpdump works
- Dec 15th, 1999
- transmission part works
- Dec 28th, 1999
- added usage of the isa_functions for Linux 2.3 . Things should
- still work with 2.0.x....
- Jan 28th, 2000
- in Linux 2.2.13, the version.h file mysteriously didn't get
- included. Added a workaround for this. Furthermore, it now
- not only compiles as a modules ;-)
- Jan 30th, 2000
- newer kernels automatically probe more than one board, so the
- 'startslot' as a variable is also needed here
- Apr 12th, 2000
- the interrupt mask register is not set 'hard' instead of individually
- setting registers, since this seems to set bits that shouldn't be
- set
- May 21st, 2000
- reset interrupt status immediately after CAM load
- add a recovery delay after releasing the chip's reset line
- May 24th, 2000
- finally found the bug in the address filter setup - damned signed
- chars!
- June 1st, 2000
- corrected version codes, added support for the latest 2.3 changes
- Oct 28th, 2002
- cleaned up for the 2.5 tree <alan@lxorguk.ukuu.org.uk>
