A kind user gave me remote access to a 7.2-RELEASE system that has
this controller. After applying latest msk(4)/mii(4) in HEAD I was
not able to reproduce the issue on Yukon Ultra controller. So would
you try latest msk(4)/mii(4) in HEAD? Just copying the related
files in HEAD(msk(4) files in /usr/src/sys/dev/msk directory and
mii(4) files in /usr/src/sys/dev/mii directory) and rebuild your
kernel.
