Stepping down ethernet card speed

[Ross Boylan <ross@biostat.ucsf.edu>]

Because of some network problems, it looks as if I need to tell my
ethernet card to operate at a certain speed, rather than letting it
autosense.  How do I do that?  Is it a run-time thing (e.g., ifconfig),
or do I need to set it as a kernel option on load?

Thanks.
