There seems to be a little inconvenience when adding/deleting blackhole 
entries, and that is since all slaves are the listeners to 
SWITCHDEV_FDB_ADD(DEL)_TO_DEVICE events and blackhole entries are not to 
any slave devices, the ops will be called for every slave device as 
there is no way to distinguish. This said, the add and del operations 
work.
