From b887250ba85424470a065b2c795d72d379b03713 Mon Sep 17 00:00:00 2001 From: Xueming Li Date: Mon, 27 Jul 2020 14:29:53 +0000 Subject: [PATCH] vdpa/mlx5: fix completion queue initialization Vdpa device failed to initialize 2nd VQ during setup. From FW syndrome, unsupported CQE size was specified in CQ initialization attributes. The unsupported CQE size comes from uninitialized stack struct data, and the struct has new fields defined recently which are not initialized in vdpa code. This patch initializes cq creation attributes with zero to avoid such random data.
