History
Robert Watson 5e71a73b7b Lock down global variables in if_tap (primarily, the tap softc list); 
add tapmtx, which protects globale variables.

Notes:

- The EBUSY check in MOD_UNLOAD may be subject to a race.  Moving the
  event handler unregister inside the mutex grab may prevent that race.

- Locking of global variables safely is now possible because tapclones
  is only modified when the module is loading or unloading, thanks to
  phk's recent chang to clone_setup().

- softc locking to follow.
