From 1c5106f66a6749266cb1d228eda98413c80cbf1f Mon Sep 17 00:00:00 2001 From: Alberto Compagno Date: Tue, 19 Feb 2019 18:46:36 +0100 Subject: [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.
