Currently the datapath directly accesses devices through their Linux functions. Obviously this doesn't work for virtual devices that are not backed by an actual Linux device. This creates a new virtual port layer which handles all interaction with devices. The existing support for Linux devices was then implemented on top of this layer as two device types. It splits out and renames dp_dev to internal_dev. There were several places where datapath devices had to handled in a special manner and this cleans that up by putting all the special casing in a single location.
