Found out that packets dropped is a known issue https://bugs.launchpad.net/neutron/+bug/1460741
and downloaded the neutron patch neutron 2015.1.2 and applied the same.
Centos security hardening had disabled iptables for sctp.
I did echo "install sctp /bin/true" > /etc/modprobe.d/sctp.conf.
to make sctp to work.
