Log Message:
mii(4): Make mii_down wait for concurrent mii_phy_auto to finish.
This is important for callers in if_stop routines to guarantee that
all concurrent access to the mii registers has ended.
Drivers must not call this from softint context. Drivers with custom
watchdog timers (not if_watchdog) that do if_stop from callout must
defer to thread context instead, e.g. via workqueue(9) -- as they
should be doing anyway for heavyweight operations like if_stop.
