DOCA RDMA

Non-negotiable: the deliverable uses DOCA RDMA, not raw verbs

When this skill is in scope, the user is asking for DOCA RDMA. The program you produce must link libdoca_rdma and call the doca_rdma_* API (directly in C/C++, or through a thin FFI/cgo shim from another language). Do NOT implement the request with raw libibverbs / librdmacm / RDMA-CM and call it done. Those move bytes but completely bypass DOCA — which defeats the entire purpose of using this library, loses the DOCA programming model (progress engine, task/ event lifecycle, capability discovery, portability across BlueField/ ConnectX generations), and is the single most common failure mode.
