This change adds a new PMDA (Performance Metrics Domain Agent) for Reliable Datagram Sockets (RDS). It exports key metrics including connection information, socket and connection statistics, and details of send, receive, and retransmit queues for performance analysis using Performance Co-Pilot (PCP).
This PMDA is intended to aid in diagnosing network-related issues on systems using RDS over Infiniband or TCP.
