Description
Sets the processing method when frames from port 1
are multicast frames.
0: CAM hit: Frames are relayed to port 0
1: CAM hit: Frames are not relayed
Sets the processing method when frames from port 1
are addressed to other than this LSI.
0: CAM hit: Frames are relayed to port 0
1: CAM hit: Frames are not relayed
Reserved
These bits are always read as 0. The write value should
always be 0.
Sets the processing method when the SA (source
address) of a frame received from port 1 is not
registered in the entry table.
0: Frame is not received
1: Frame is received
However, a frame discarded because of the VLANtag

If a frame whose source address is not registered in the
entry table has been received, a carrier extension error
is issued regardless of whether the frame is received or
not.
Reserved
These bits are always read as 0. The write value should
always be 0.
