Two mentions of problems with manually configured gigabit operation.

Is there really a problem in that scenario?  Shouldn't be.

Regardless of what the UI appears to be doing, you can't do gigabit without autonegotiating.  It shouldn't be possible to create a duplex mismatch on a gig link.

Either I'm confused, or this should be added to the list of myths that need debunking.
