paRoutePriIntf_e is used to specify the mode of priority-based or interface-based routing. PASS forwards the matched packets to the desired QoS queue which is equal to the base queue plus an offset specified by the VLAN priority or DSCP value in prority-based routing. PASS forwards the matched packets to the desired host queue which is equal to the base queue plus an offset as the EMAC port (interface) number with the CPPI flow which is equal to the base flow number plus the EMAC port (interface) number optionally in interface-based routing.
- Note:
- : There is some use cases where output packets from QoS are delivered to PASS for pre-routing operation such as tx timestamp report and both egress and ingress forwarding packets go through the same QoS. To support this use case, the PASS is enhanced to delay the post-classification command set execution until the packets re-entering PASS from QoS if Priority-based routing is selected.
