Hello all, This patch set introduces the Elastic RDMA Adapter (ERDMA) userspace provider driver of *rdma-core*, and this patch set is used for review purpose. The kernel driver of ERDMA can refer this link [1]. The main feature of ERDMA userspace provider includes: supports RC QP, supports RDMA Write/Send/RDMA Read/Immediate opcode in post_send, supports post_recv, and supports CQs with polling mode and event mode. Now we does not support SRQ yet. Thanks, Cheng Xu [1] https://lwn.net/Articles/879373/ Cheng Xu (5): RDMA-CORE/erdma: Add userspace verbs related header files.
