Btw, a forwarding strategy needs to know the necessary parameters to create
a face. You can attach these information to an Interest or Data using NDNLP
field and tag.

 We are not taking this design. The current NFD supports both Ethernet
multicast and unicast with separate faces. You don't need to implement #4283
<https://redmine.named-data.net/issues/4283> if you just want to create a
unicast face in a forwarding strategy.
