Subject: [PATCH v2] examples/vhost: fix floating point exception when no VMDq
Date: Wed, 18 May 2022 21:36:33 +0800 [thread overview]
Message-ID: <20220518133633.1634902-1-yuanx.wang@intel.com> (raw)
In-Reply-To: <20220411163451.572814-1-yuanx.wang@intel.com>
If the VMDQ limits is 0, a divide-by-zero error occurs.
This patch replaces throwing a floating point exception with
a normal error message.
Fixes: d19533e86f ("examples/vhost: copy old vhost example")
