Enable Partition Detection
Not Discard RX Packets when Ingress Bandwidth Control
When received packets bandwidth reach Ingress bandwidth threshold,
the packets over the threshold are not discarded but with flow control.
Flow control in full duplex mode, or back pressure in half duplex mode
enable
0: enable
1: disable
Bandwidth Control
0: Control with Ingress and Egress separately, ref to Register 66H.
1: Control with Ingress or Egress, ref to Register 67H
Broadcast packet filter
0: accept broadcast packets
1: reject broadcast packets
Multicast packet filter
0: accept multicast packets
1: reject multicast packets
Broadcast Storm Control
0: only broadcast packets storm are controlled
