Also the UDP checksum in the IKE_SA_INIT response shows incorrect in wireshark.

Subject: IKE_SA_INIT response with notification data missing
I am trying to establish a IKEv2/IPsec tunnel from a security gateway towards strongswan with strongswan acting as a responder. In response to IKE_SA_INIT request packet, strongswan sends back IKE_SA_INIT response with a Notify payload of MULTIPLE_AUTH_SUPPORTED with notification data missing. I have attached the wireshark. It would be great if someone can explain why this behavior.
[IKEv2]$ ipsec --version
Linux strongSwan U5.3.0/K3.8.13-16.2.1.el6uek.x86_64

The following is the configuration.
