From 571fb4fb78a3bf0fcadbe65eca9ca4ccee885af4 Mon Sep 17 00:00:00 2001 From: Haoyue Xu Date: Fri, 29 Oct 2021 17:58:46 +0800 Subject: [PATCH] RDMA/hns: Fix initial arm_st of CQ We set the init CQ status to ARMED before. As a result, an unexpected CEQE would be reported. Therefore, the init CQ status should be set to no_armed rather than REG_NXT_CEQE.
