 I don't know much about this code but non-NULL ifp->if_sadl value
 early in the boot process looks suspicious to me:
 
         /*
          * If the interface already has a link name, release it
          * now.  This is useful for interfaces that can change
          * link types, and thus switch link names often.
          */
         if (ifp->if_sadl != NULL)
                 if_free_sadl(ifp);
 
 or may be it's normal because iwm init has been deferred.
