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.
