ethtool failure with tulip 21143

[Stefan Jeglinski]

I have a PowerPC 6500 with a Farallon 10/100 PCI card connected to a
Netgear 10/100 switch. I have never gotten this card to work right in
this box. If the number of packets is small, the connection seems to
work, but any increase in the number of packets (my theory) causes
the interface/NIC to choke up. I'm using 2.4.14 (bk).

I downloaded Jeff Garzik's ethtool to work on this, but I'm hitting a
brick wall rather rapidly. As per dmesg:

[root at orion ethtool-1.4]# dmesg
Linux Tulip driver version 0.9.15-pre8 (Oct 11, 2001)
PCI: Enabling device 00:0e.0 (0000 -> 0003)
tulip0:  EEPROM default media type Autosense.
tulip0:  Index #0 - Media 10baseT (#0) described by a 21142 Serial
PHY (2) block.

eth0: Digital DS21143 Tulip rev 65 at 0xc81f2000, 00:00:C5:53:3E:3D, IRQ 25.


I can get some basic information with the -i switch:

[root at orion ethtool-1.4]# ethtool-i eth0
driver: tulip
version: 0.9.15-pre8
firmware-version:
bus-info: 00:0e.0


But any attempts to get (much less set) anything else fail in this fashion:

[root at orion ethtool-1.4]# ethtool eth0
Settings for eth0:
No data available

Trying the register dump yields:

[root at orion ethtool-1.4]# ethtool -d eth0
Cannot get register dump: Operation not supported

I've tried this in a completely different box (9500) with the same
card, and get the same result. Does ethtool not work with the 21143
Tulip?
