Hi Neil,
the link bonding device is essentially a software PMD, and as such supports all the standard PMD APIs, the only new APIs which the link bonding library introduces  are for the control operations of the bonded device which are currently unsupported by the standard PMD API. Operations such as creating, adding/removing slaves, and configuring the modes of operation of the device have no analogous APIs in the current PMD API and required new ones to be created .
