[PATCH for-next 13/20] RDMA/hns: Configure mac&gid and user access region for hip08 RoCE driver

Wei Hu (Xavier)
2017-08-30T09:23:11Z

In hip08, the user access region(UAR) pfn is calculated
from pci device memory resource.

This patch mainly sets mac and gid table by configuring
the relevant registers and updates the uar pfn for hip08 SoC.
