Advanced VLAN features, such as “Ingress VLAN filtering” and “Discard Non PVID packets” are also supported by the
KS8993F. These features can be set on a per port basis, and are defined in register 18, bit 6 and 5, respectively for
port 1.
2.9.3
QoS Priority
This feature provides Quality of Service (QoS) for applications, such as VoIP and video conferencing. The KS8993F
per port transmit queue could be split into two priority queues: a high priority queue and a low priority queue. Bit 0 of
registers 16, 32 and 48 is used to enable split transmit queues for ports 1, 2 and 3, respectively. Optionally, the
Px_TXQ2 strap-in pins can be used to enable this feature. With split transmit queues, high priority packets will be
placed in the high priority queue and low priority packets will be placed in the low priority queue.
For split transmit queues, the KS8993F provides four priority schemes:
