Support DS EF Code.
0 – Disable (Default)
1 – Enable (all ports)
When 101110 is detected in DS field (TOS[7:2]), the frame priority is set for
110 and drop is set for 0.
Reserved. Must be 0.
Reserved. Must be 1.
Report to CPU
0 – Disable (Default)
1 – Enable
When disable new MAC address report or aging reports are disable for all
ports. When enable, register SE_OPMODE is used to enable/disable
selectively each function.
MII Management State Machine
0: Enable (Default)
1: Disable
This bit must be set so that there is no contention on the MDIO bus between
MII Management state machine and MIIC & MIID PHY register accesses.
MCT Link List structure
0 – Enable (Default)
1 – Disable
