-
- As of April 2001 this driver should support most tulip cards that
- the Linux tulip driver supports because Donald Becker's Linux media
- detection code is now included.
-
- Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
- Linux Tulip Driver. Supports N-Way speed auto-configuration on
- MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
- based on the Macronix MX987x5 chip, such as the SOHOware Fast
- model SFA110A, and the LinkSYS model LNE100TX. The NetGear
- model FA310X, based on the LC82C168 chip is supported.
- The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
- chipset is supported. Also, Davicom DM9102's.

- Some code fragments were taken from verious places, Ken Yap's
- etherboot, FreeBSD's if_de.c, and various Linux related files.
- DEC's manuals for the 21143 and SROM format were very helpful.
- The Linux de driver development page has a number of links to
- useful related information. Have a look at:

- 08 Feb 2005 Ramesh Chander chhabaramesh at yahoo.co.in added table entries
- for SGThomson STE10/100A
- 07 Sep 2003 timlegge Multicast Support Added
- 11 Apr 2001 mdc [patch to etherboot 4.7.24]
- Major rewrite to include Linux tulip driver media detection
- code. This driver should support a lot more cards now.
- 16 Jul 2000 mdc 0.75b11
- Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
- which is used on the LinkSYS LNE100TX v4.x cards. We already
- support LNE100TX v2.0 cards, which use a different controller.
- 04 Jul 2000 jam ?
- Added test of status after receiving a packet from the card.
- Also uncommented the tulip_disable routine. Stray packets
- seemed to be causing problems.
- 27 Apr 2000 njl ?
- 29 Feb 2000 mdc 0.75b7
- Increased reset delay to 3 seconds because Macronix cards seem to
- need more reset time before card comes back to a usable state.
- 26 Feb 2000 mdc 0.75b6
- Added a 1 second delay after initializing the transmitter because
- some cards seem to need the time or they drop the first packet
- transmitted.
- 23 Feb 2000 mdc 0.75b5
- removed udelay code and used currticks() for more reliable delay
- code in reset pause and sanity timeouts. Added function prototypes
- and TX debugging code.
- 21 Feb 2000 mdc patch to Etherboot 4.4.3
- Incorporated patches from Bob Edwards and Paul Mackerras of
- Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
- and udelay. We now wait for packet transmission to complete
- (or sanity timeout).
- 04 Feb 2000 Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
- patch to tulip.c that implements the automatic selection of the MII
- interface on cards using the Intel/DEC 21143 reference design, in
- particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
- 21143-PD chipset.
- 11 Jan 2000 mdc 0.75b4
- Added support for NetGear FA310TX card based on the LC82C168
- chip. This should also support Lite-On LC82C168 boards.
- Added simple MII support. Re-arranged code to better modularize
- initializations.
- 04 Dec 1999 mdc 0.75b3
- Added preliminary support for LNE100TX PCI cards. Should work for
- PNIC2 cards. No MII support, but single interface (RJ45) tulip
- cards seem to not care.
- 03 Dec 1999 mdc 0.75b2
- Renamed from mx987x5 to tulip, merged in original tulip init code
- from tulip.c to support other tulip compatible cards.
- 02 Dec 1999 mdc 0.75b1
- Released Beta MX987x5 Driver for code review and testing to netboot
- and thinguin mailing lists.
