Huge Packet
Support
R/W
=1, Will accept packet sizes up to 1916 bytes (inclusive). This bit setting will
override setting from bit 1 of this register.
=0, The max packet size will be determined by bit 1 of this register.

Packet Size Check
Enable
R/W
=0, Will accept packet sizes up to 1536 bytes (inclusive).
=1, 1522 bytes for tagged packets, 1518 bytes for untagged packets. Any
packets larger than the specified value will be dropped.

802.1Q VLAN
Enable
R/W
=1, 802.1Q VLAN mode is turned on. VLAN table needs to set up before the
operation.
=0, 802.1Q VLAN is disabled.

IGMP Snoop Enable
on Switch MII
Interface
R/W
=1, IGMP snoop is enabled. All IGMP packets will be forwarded to the Switch
MII port.

Fair Queue
Enable
R/W
=0, Priority method set by the registers 175-186 bit [7]=0 for port 1, port 2 and
port 3.
=1, Weighted Fair Queueing enabled. When all four queues have packets waiting
to transmit, the bandwidth allocation is q3:q2:q1:q0 = 8:4:2:1.
If any queues are empty, the highest non-empty queue gets one more weighting.
For example, if q2 is empty, q3:q2:q1:q0 becomes (8+1):0:2:1.

Sniff Mode Select
R/W
=1, Will do RX AND TX sniff (both source port and destination port need to
match)
=0, Will do RX OR TX sniff (either source port or destination port needs to
match). This is the mode used to implement RX only sniff.
