Subject: [dpdk-dev] [PATCH 02/12] lib/librte_vhost: add vhost_user private info structure
Date: Mon, 27 Nov 2017 20:01:05 +0000 [thread overview]
Message-ID: <20171127200115.31049-3-roy.fan.zhang@intel.com> (raw)
In-Reply-To: <20171127200115.31049-1-roy.fan.zhang@intel.com>
This patch adds a vhost_user_dev_priv structure and a vhost_user
message handler function prototype to vhost_user. This allows
different types of devices to add private information and their
device-specific vhost-user message function handlers to
virtio_net structure. The change to vhost_user_msg_handler is
also added to call the device-specific message handler.
