Chandramohan Akula developed BNXT-R WR API support and enhanced PSN/MSN handling in the amzn/rdma-core repository, focusing on expanding RDMA capabilities for high-throughput workloads. He reorganized the queue pair creation logic to enable WR API integration and implemented new send operations, including RDMA write, read, and atomic functions, using C and low-level network programming techniques. His work improved the correctness of PSN/MSN management across various queue types and packet lengths, addressing reliability and maintainability concerns. By refactoring core driver components, Chandramohan laid the groundwork for future WR API features and strengthened production readiness for BNXT-R in RDMA environments.
