I use a 3C575 on a ToPIC95/07 laptop. I use it at home and in my office, and I switch between the two configs with "cardctl scheme <xxx>". The default scheme is "home".
When I use my laptop in my office, I get the folowwing error messages:
Dec 1 16:20:43 notebook kernel: eth0: Transmit error, Tx status register 82. Dec 1 16:25:18 notebook last message repeated 201 times
Also all I can get through over the office net is exactly 220kBytes/s in our 100Mbit net! Yes, it's true, it's exactly 220kBytes/s every time I test it out! At home (also 100Mbit) I get the all that my harddisk can do, so I'm wondering what might be the reason for that.
