Maybe. Newer dec-tulips (like the 21143), cannot be reliably put into
100-fdx mode with the current BSD driver. I've been complaining about
this for years.
Jason Thorpe mentioned he was working on a new tulip driver. When
that's ready, we can hope it will fix the problem. Until then, try
putting your switches (&cards) into half-duplex mode.
Cheers,
Drew
