Hi, Or Gerlitz

1.  Oulijun resloved the problem, and sent PATCH V6 on 2016-4-28. Thanks 
for more comments.

2.  This driver for Hisilicon RoCE Engine run in ARM SoCs.

The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoCs. HNS(Hisilicon Network Subsystem)
has a hardware support of performing RDMA with RoCE engine.

This Kconfig related with this driver as below:

config INFINIBAND_HISILICON_HNS
     tristate "Hisilicon Hns ROCE Driver"
     depends on NET_VENDOR_HISILICON
     depends on ARM64 && HNS && HNS_DSAF && HNS_ENET
