conntrack: Fix to avoid duplicate connections in initial burst
JIRA: SAMPLEVNF-43 Before connection setup, if there are multiple packets in the burst and are belongs to same connection, it was adding new connection for the same 5 tuple connection, leading to multiple connections in the CT. It was causing more number of active connections than possible. Change-Id: I15c90e7feb465d96a9429ea6fedcb09fad9482e6 Signed-off-by: Anand B Jyoti <anand.b.jyoti@intel.com>
