State-Changed-Why: 
The BCM5704 appears to have some special (and undocumented) registers
that have to be set to properly advertise flow control ability when
autonegotiating with a switch in TBI/fiber mode. I added code to
the bge(4) driver to set these registers during autoneg, and the
link seems to be properly negotiated now, and traffic is exchanged
correctly. A patch for this problem is available at
http://www.freebsd.org/~wpaul/bge.diff. This patch has been supplied
to the submitter and checked in to the FreeBSD-current sources.
