How to emulate RoCEv2 flows

What is RoCEv2?

RoCEv2 (RDMA over Converged Ethernet version 2) is a network protocol that enables remote direct memory access (RDMA) over routable IP networks using UDP encapsulation. RDMA is a high-performance protocol that allows servers to directly read from or write to the memory of another server without involving the CPU, operating system, or intermediate data copying. This is commonly used in high-speed data center networks to reduce latency and CPU overhead.
