Bit 7: LAN Port 2 MAC Interrupt Mask control (LP2MIM)
Bit 6: LAN Port 2 Queue Overflow Mask (LP2QOM)
0 = SU.LIQOS.LIQOS2 will not generate an interrupt.
1 = SU.LIQOS.LIQOS2 will generate an interrupt.
Bit 5: LAN Port 2 FIFO Reset (LP2FR)
0 = Normal operation.
1 = Reset the LAN 2 receive FIFO. The MAC Receiver should be disabled during FIFO reset.
Bit 4-3: LAN Port 2 Priority Forwarding/Scheduling (LP2PF[2:1]).
Bit 2-1: LAN Port 2 Ethernet VLAN Tag Function Enable (LP2ETF[2:1]). The Ethernet VLAN Tag functions
are not required to be enabled for Priority Scheduling (LP1PF = 01/10).
Bit 0: LAN Port 2 Enable (LP2E).
The L2PE = 1 (Enabled) is only valid when LPM = 1 (Dual Port) and when in Forwarding Modes 2, 4, or 5.
Otherwise, the device should be configured to L2PE =0 (Disabled).
When LAN Port 2 Priority Forwarding or Priority Scheduling has been enabled, the user must also configure the
Priority Table and No Priority Detected registers.
When LAN Port 2 Ethernet Tag Forwarding has been enabled, the user must also configure the Ethernet Tag Table
and No Ethernet Tag Detected registers.
