We do have a common layer it is called the ethdev layer. The ethdev layer provides a common and generic API’s for the application to use and requires PMDs to register a set of function pointers to ethdev. These function pointers are common and generic to all of the PMDs. As for the PMDs it is impossible to have a cleaner solution unless every NIC is programmed in the same why. The two layer device model is used in just about all OS types like Linux, Windows, FreeBSD, … as this appears to be the best solution until you can get every vendor in the world to pick a single hardware interface.
