[dpdk-dev] [PATCH] ethdev: The users could get device types now

[Ding Heng <hengx.ding@intel.com>]

As different PMDs support different features, application may want
to know the NIC type of a port, then decide how to use that port.
Add a new field in struct rte_eth_dev, users are able to get
device type now.
