Methods and systems in a network device for efficient I/O transfer from a network device to an application are presented. In one embodiment, information regarding metadata is received. The metadata is to be used by an application for processing packets received through the network interface of network interface system. A metadata data structure is determined based on the information. The metadata data structure is customized for the application. The application is updated with the metadata data structure, and the network interface system is notified with of the metadata data structure. The notification causes the network interface system to transfer metadata to the application according to the metadata data structure.
