Nxpwifi is a two modules driver: one for core layer and another one is for bus driver. Core layer supports needed functions to allow bus driver to create an working instance for the bus driver. Struct nxpwifi_if_ops is defined to allow bus driver to hook callback functions to core layer for the operations of bus related functions.
