Bits 0-15: LAN Extract Ethernet Type (LEET[16:1]). This value defines the 2-byte Ethernet Protocol Type
that the LAN Trap is to monitor for. Bits 0 to 7 are used to define the least significant byte. One example setting is
08-06 (hex) for Ethernet Type = ARP.

Bit 7: LAN Port 1 MAC Interrupt Mask control (LP1MIM)
Bit 6: LAN Port 1 Queue Overflow Mask (LP1QOM)
0 = SU.LIQOS.LIQOS1 will not generate an interrupt.
1 = SU.LIQOS.LIQOS1 will generate an interrupt.
Bit 5: LAN Port 1 FIFO Reset (LP1FR)
0 = Normal operation.
1 = Reset the LAN 1 receive FIFO. The MAC Receiver should be disabled during FIFO reset.
Bits 3-4: LAN Port 1 Priority Forwarding (LP1PF[2:1])
Bit 1-2: LAN Port 1 Ethernet VLAN Tag Function Enable(LP1ETF[2:1]). The Ethernet VLAN Tag functions
are not required to be enabled for Priority Scheduling (LP1PF = 01/10).
Bit 0: LAN Port 1 Enable (LP1E)
