Locking in the sense that certain parts have to be protected by splimp/splx.
You can always replace the mutex locking with splimp, with the exception of
removing the unlocking / locking pair around (*ifp->if_inut)(ifp, m), but
such a call shouldn't exist. That's the save approach, we can always remove
such calls later, they might only reduce performance a bit.
