Hello,
I have the following weirdosity with some of my eepro100 cards, on
2.3.99-preX. Specifically, the problem only seems to occur on the
cards with addresses in the range 00:A0:C9:xx:xx:xx, and not the
cards with mac addresses in the range 00:90:27:xx:xx:xx.
The pings are from 15.5.2.43 to 15.5.2.42 (the problem is on the
latter). The tcpdump was captured on another system on the same
ethernet.
thanks,
karthik
The cards with the problem:
