I'll let Donald answer this question :-)
But you could also check the archives of this list and others and 
scyld.com as the answer was repeated several times.

This is what you should always use. Maybe after seeing Donald's answer 
you'll understand why :-)

This is correct at least for the current Scyld driver which always uses
the MII transceiver in autonegotiate mode for these cards. By forcing
full-duplex, the half-duplex capabilities are not advertised anymore.
Which means that actually this is not a "force force" situation, but again
a "force auto"  situation.

Yes, IMHO this is how switches should also behave...

That's correct; see
