The series adds inline protocol support in ipsec-secgw application. First patch introduces changes in lib to enable applications to save a 64 bit metadata in security session. For inline processed packets, application could call "rte_security_get_pkt_metadata" API to retrieve this application registered metadata from the packet. API will return the metadata associated with the security session which processed the packet.
This is primarily required for inline protocol processed ingress packets. For such packets, the packet may not have enough information to identify the security parameters with which the packet was processed. Application can register what it needs to identify the required parameter. The metadata will be set while creating the security session. Second patch adds support for inline protocol in ipsec-secgw application.
