[for-next,0/5] RDMA/hns: Refactor process of buffer allocation and calculation

Message

Patch #1 and #2 aim to use MTR interfaces for PBL buffer instead of MTT,
and after this, MTT can be removed completely. Patch #3 and #5 refactor
buffer size calculation process for WQE and SRQ. #4 can be considered as a
preparation for #5, which just moves code of SRQ together to a more
suitable place.

This series looks huge, but most of the modification is to replace and
remove old interfaces, and patch #4 also contribute a lot. Actually, the
original logic is not changed so much.

Xi Wang (4):
  RDMA/hns: Optimize PBL buffer allocation process
  RDMA/hns: Remove unused MTT functions
  RDMA/hns: Optimize WQE buffer size calculating process
  RDMA/hns: Optimize SRQ buffer size calculating process

  RDMA/hns: Move SRQ code to the reasonable place
