RSS_Priority 25 RW 0x0 This bit enables the receive packet to choose

instead of RC class when both RSS and RC rules
are matched. Default is to give priority to RC.
RC Return Ring Enable 24 RW 0x0 1: Enable receive packet to use RC rule class as
return ring number if RC rule is matched. This bit
will be used in conjunction with bit25 to derive the
