Optional properties for ports:
- defqpri=<n> : Enforced default queue priority for the given port.
Valid range is 0..3
+- schedule=<n> : Set ports scheduling mode. Valid values are:
+ MV88E6XXX_PORT_SCHED_ROUND_ROBIN - All output queues
+ use a weighter round robin scheme.
+ MV88E6XXX_PORT_SCHED_STRICT_3 - Output queue 3 uses
+ a strict scheme, where any packets in queue 3 will be
+ egressed first, followed by weighted round robin for
+ the other ports.
+ MV88E6XXX_PORT_SCHED_STRICT_3_2 - Output queue's 2
+ and 3 use strict, other use weighted round robin.
+ MV88E6XXX_PORT_SCHED_STRICT_ALL - All queues use
+ strict priority, where queues drain in descending
+ queue number order.
