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
