- Corrected PDCP layer to manage more than one UE correctly * use eNB_id, UE_id as identifiers for connections * splitted UE/eNB data * Use the real rb_id for index in array (instead of the one used for communication with RLC/IP driver pre-ci OK, except for the random issue related to Msg3 git-svn-id: http://svn.eurecom.fr/openair4G/trunk@4730 818b1a75-f10b-46b9-bf7c-635c3b92a50f
