Subject: [dpdk-dev] [PATCH] test: fix division by zero
Date: Fri, 23 Apr 2021 15:35:30 +0800 [thread overview]
Message-ID: <1619163330-25960-1-git-send-email-humin29@huawei.com> (raw)
Variable i is used as a denominator which may be zero, and
this may result in segmentation fault.
This patch fixed it.
Fixes: 948bc3d6d095 ("test: add reciprocal based division")
Cc: stable@dpdk.org
Signed-off-by: Min Hu (Connor) <humin29@huawei.com>
