[tulip] LNE100TX rev. 5.0

[Jacob Schroeder]

Here's the full detection message as seen in "/var/log/messages".

Dec 12 10:11:34 jacob kernel: tulip.c:v0.91g-ppc 7/16/99 becker@cesdis.gsfc.nasa
.gov
Dec 12 10:11:34 jacob kernel: eth0: ADMtek Centaur-P rev 17 at 0xdc00, 00:04:5A:
52:C7:36, IRQ 11.

The hub is a repeater (a somewhat old 10Mbps Linksys with 8 RJ-45 ports and 1 BNC). ifconfig for this NIC currently shows 382,699 RX packets, 993,522 TX packets and 232,851 collisions with 0 receive or transmit errors. 

I'll try 0.93 as soon as I can get everything compiled right. 0.91 is the newest tulip ver. Debian potato has right now (2.2.19 kernel).

Thanks,
Jacob
