The series adds inline protocol support in DPDK. First patch introduces changes in lib to enable applications to save a (void *) pointer as "userdata" in security session. For inline processed packets, applications would use the metadata field in the mbuf (rte_mbuf.udata64) to retrieve the userdata registered for the security session which processed the packet. The metadata would be device specific.
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 userdata will be set while creating the security session.
