Tulip and clone Etherboot Driver

|
||
|
||
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.

DEC's manuals for the 21143 and SROM format were very helpful.

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.
