From 391bd5fc7de54a5cb866e8897d60ee1d76b8840a Mon Sep 17 00:00:00 2001 From: oulijun Date: Fri, 4 May 2018 10:57:08 +0800 Subject: [PATCH] RDMA/hns: Not support qp transition from reset to reset for hip06 Because hip06 hardware is not support for qp transition from reset to reset state, it need to return errno when qp transited from reset to reset. This patch fixes it.
