Description
=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.
=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.
Reserved
Do not change the default value.
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.
Reserved
Do not change the default values.
Reserved
Do not change the default values.
=0, Always transmit higher priority packets first
=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.
Reserved
Do not change the default values.
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.
