The XGMAC_HWFEAT_GMIISEL bit also indicates whether support 10/100Mbps or not. The XGMAC_HWFEAT_HDSEL bit indicates whether support half duplex or not. The XGMAC_HWFEAT_ADDMACADRSEL bit indicates whether support Multiple MAC address registers or not. The XGMAC_HWFEAT_SMASEL bit indicates whether support SMA (MDIO) Interface or not.
