From 023c1477b0d0b123c0dec6466ec568a25928bef2 Mon Sep 17 00:00:00 2001 From: "Wei Hu(Xavier)" Date: Thu, 26 Oct 2017 17:10:24 +0800 Subject: [PATCH] RDMA/hns: Generate gid type of RoCEv2 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.
