There are some issues when using SRQ on HIP08/HIP09, the first part of this
series is some fixes on them.

In addition, the codes about RQ/SRQ including the creation and post recv
flow are a bit hard to understand, they need to be refactored.

Lang Cheng (2):
  RDMA/hns: Allocate one more recv SGE for HIP08
  RDMA/hns: Use new interfaces to write SRQC

Wenpeng Liang (8):
  RDMA/hns: Bugfix for checking whether the srq is full when post wr
  RDMA/hns: Force srq_limit to 0 when creating SRQ
  RDMA/hns: Fixed wrong judgments in the goto branch
  RDMA/hns: Remove the reserved WQE of SRQ
  RDMA/hns: Refactor hns_roce_create_srq()
  RDMA/hns: Refactor code about SRQ Context
  RDMA/hns: Refactor hns_roce_v2_post_srq_recv()
  RDMA/hns: Add verification of QP type when post_recv

Xi Wang (2):
  RDMA/hns: Refactor post recv flow
  RDMA/hns: Clear remaining unused sges when post_recv
