Subject: [PATCH net-next v2 07/21] motorcomm:yt6801: Implement the fxgmac_init function
Implement the fxgmac_init to init hardware settings, including setting function
pointers, default configuration data, irq, base_addr, MAC address, DMA mask,
device operations and device features.
It alseo populates the hardware features, initialize RSS hash key and lookup
table and other configure.
