Speed and duplex are set independently of each other.  It does not
matter what you set the speed to, it only matters that you forced the
duplex setting on one end of the link, without forcing the same setting
on the other end of the link.

The rule is that both ends of the link must use the same settings,
either both forced, or both auto.

It turns out that speed settings can be reliably detected by the other
end of the link, but duplex can NOT.  A duplex mismatch is thus a very
common condition, and is usually only detected by "slow network
response" being the symptom.
