The PHY driver on the miibus is reporting status to the msk NIC
driver. That driver interprets the status. While it is
autonegotiating for line speed, the registers report garbage/bouncing
of the line. You need to defer reporting the change a little during
autonegotiation. The code to do this is somewhere in dev/mii. I'm
not sure what other drivers have to cope with this issue, but have
observed this behavior on a number of occasions...
