72  The use-case is that, for some unspecified reason, the control plane
73  has a very different set of entries it wants in the table than VPP
74  currently has. The CP would thus like to 'replace' VPP's current table
75  only by specifying what the new set of entries shall be, i.e. it is not
76  going to delete anything that already exists.
77  the CP declares the start of this procedure with this begin_replace
78  API Call, and when it has populated all the entries it wants, it calls
79  the below end_replace API. From this point on it is of course free
80  to add and delete entries as usual.
81  The underlying mechanism by which VPP implements this replace is
82  purposefully left unspecified.
