+ *  Add a 'special' entry to the FIB.
  *  A special entry is an entry that the FIB is not expect to resolve

- *  Instead the client/source provides the adj to link to.
+ *  Instead the will link to a DPO valid for the source and/or the flags.
  *  This add is reference counting per-source. So n 'removes' are required
