[HICN-71]
- Handling the case in which a pushed data hit an existing pit entry (created after the data has gone through the data_pcslookup_node). In this case the data packet is forwarded to the data_fwd_node - Handling the case in which the hash table (in pcs) is full and it is not possible to allocate another bucket. In this case the packet is dropped. - Copying packets whose length is less than 128B. VPP prevents to create a chain of vlib_buffer where the first, or middle, vlib_buffer are holding less then 128B. [HICN-72] - Assign a /128 subnet to the producer app face. Change-Id: I6c19d6d127774a7f59ac69ac965d4bcd6a72becc Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>
