Direct wqe is a mechanism to fill wqe directly into the hardware. In the
case of light load, the wqe will be filled into pcie bar space of the
hardware, this will reduce one memory access operation and therefore
reduce the latency. 

This series first refactor current uar mmap process to add branch for
direct wqe, then fix an issue on interface to write doorbell, the feature
is enabled at last.

The kernel parts is named "RDMA/hns: Add support for userspace Direct WQE".

Hi,

This series extends librdmacm to unique identify the IBV device
connected to the CMA device.

Thanks
