3Com 3c905B-TX showing up as xl0

plugged in using a etl certified (whooie) cat-5e to:

Linksys EtherFast 4116

Using ping -f /{some address}/, I've noticed at these configured speeds
the following:

10baseT/UTP half-duplex == 11% packet loss
10baseT/UTP full-duplex == 30% packet loss
100baseTX half-duplex == 70-80% packet loss
100baseTX full-duplex == 95-99% packet loss

Some older cards simply won't handle the data rate of a flood ping; if you can do something like:


ping -s 1000 -i 0.001 _address_

...without packet loss, it's probably fine to use for normal purposes. The only other response I can think to give is to try swapping in a high-end card like a fxp.
