Ah ha!  That might be the problem: is the switch you are connected to
set to forced full duplex?  If so, you will have force the driver to
full duplex mode.

If that fixes the symptoms, we might have a problem with handling
out-of-window collisions.  They should be handled automatically by the
hardware, but the driver might need to do something special to handle
this type of network error.
