This is [1/3] part of hinic3 Ethernet driver initial submission. With this patch hinic3 is a valid kernel module but non-functional driver. The driver parts contained in this patch: Module initialization. PCI driver registration but with empty id_table. Auxiliary driver registration. Net device_ops registration but open/stop are empty stubs. tx/rx logic. All major data structures of the driver are fully introduced with the code that uses them but without their initialization code that requires management interface with the hw.
