Description
1 = 802.1Q VLAN mode is turned on. VLAN table needs to set
up before the operation.
0 = 802.1Q VLAN is disabled.
1 = IGMP snoop is enabled. All IGMP packets will be forwarded
to the Switch MII port.
0 = IGMP snoop is disabled.
IPv6 MLD snooping
1 = Enable
0 = Disable
IPv6 MLD snooping option
1 = Enable
0 = Disable
0 = Always transmit higher priority packets first
1 = Weighted Fair Queuing 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.
Reserved
Do not change the default values.
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.
Description
1 = Enable repeater mode
0 = disable repeater mode
Note: For repeater mode, all ports need to be set to
100Base-TX and half duplex mode. PHY ports need to have
auto-negotiation disabled.
1 = Enable MII interface half-duplex mode.
0 = Enable MII interface full-duplex mode.
