Subject[PATCH 2/3] RDMA/hns: Generate gid type of RoCEv2
Date
HNS_ROCE_CAP_FALG_ROCE_V1_V2 is added for selecting capability of
RoCE in hns driver. When HNS_ROCE_CAP_FALG_ROCE_V1_V2 is set,
driver will inform ib core that the related hns device can support
RoCEv2, and ib core can generate the gid of the related type.
