Subject: [dpdk-dev] [PATCH v2] vhost: add device reset status
Date: Mon, 10 Aug 2020 13:11:05 +0000
Message-ID: <20200810131105.17006-1-chenbo.xia@intel.com> (raw)
In-Reply-To: <20200806113455.82766-1-chenbo.xia@intel.com>

vhost lib now does not have definition of reset status. This patch
adds the reset status definition and changes related log.
