Description
–
This bit enables the receive packet to choose
receive return ring in terms of RSS hash value
instead of RC class when both RSS and RC rules
are matched. Default is to give priority to RC.
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
final receive return ring.
0: Disable receive packet to use RC rule class as
return ring number. Receive packet only uses
RSS hash to select the receive return ring. If no
any RSS hash types are applied, the default ring
0 will be used.
1: Disable CPU priority over SDC when
arbitrating the MACTQ write requests.
0: Enable CPU priority over SDC when
arbitrating the MACTQ write requests.
