PVMODE
Reserved. Must be 0.
Slow learning (Default = 0)
Same function as SE_OPMODE bit [7]. Either bit can enable the function; both need to
be turned off to disable the feature.
Disable dropping of frames with destination MAC addresses 01-80-C2-00-00-01 to
0x01-80-C2-00-00-0F.
0: Drop all frames in this range (Default)
1: Disable dropping of frames in this range
Flooding control in secure mode
0: Enable - Learning disabled port will not receive any flooding packets (Default)
1: Disable
Support MAC address 0
0: MAC address 0 is not learned. (Default)
1: MAC address 0 is learned.
Disable IEEE multicast control frame (01-80-C2-00-00-00 to 01-80-C2-00-00-FF) to
CPU in managed mode. In unmanaged mode, frame is forwarded as multicast (except
PAUSE frame).
0: Frame is forwarded to CPU (Default)
1: Frame is forwarded as multicast (except PAUSE frame)
Reserved. Must be 0.
Enable logical port match in secure mode
0: Disable (Default)
1: Enable - When Well Known or User Define logical port force discard enabled, force
any IP packet with logical port number matching logical port numbers to CPU.
This means packet with destination MAC address 0 is forwarded as unknown
destination. It is subjected to unicast to multicast rate control.
