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...
