It's very simple. The devices at each end of a TP cable can autodetect
speed. However, if the duplex mode is locked (set manually) at one end
(whether it is locked at half or full duplex), you *cannot* depend on
the other end to get the correct duplex mode. Sometimes it will work,
sometimes it won't.

Thus the advice to either use auto-negotiate everywhere, or use manual
everywhere. One end auto-negotiate and one end manual is a recipe for
disaster.
