Hello,
I am experiencing some weird problems with the dc-driver for a specific
ethernet-card ... the Compex Freedomline (10/100 Mbps).
The card perfectly seems to autodetect the mode it should operate on and
seems to indeed be working just fine just after the system has booted up.

Downloading an 128 MB-file from the network to /dev/null results in speeds
like 9.8 MB/s (close to the theoretical maximum for a 100 Mbps network)
After a (little) while though network performance almost comes to a halt
somewhere around 6 to 32 kB/s ... and never seems to "recover" again.

Anybody that could help me out trying to figure out why the card seems to
break down like this ?

Managers know it must be good because the programmers hate it so much.
