UDP-Encap: name counters for the stats segment
change the ADD api so that is returns the 'ID' that can be used by the client to read the stats from the stats segment and to delete the object. Previously a similar value used required to be chosen by the client, now VPP allocates one (like it does e.g. for interfaces) Change-Id: I563cf6092276eb990c52d5457c86e72546bcf69e Signed-off-by: Neale Ranns <nranns@cisco.com>
