> +Description
> +===========
> +
> +This document provides the plan for testing the Rte_flow Priority feature.
> +this feature uses devargs as a hint to active flow priority or not.
> +
> +This test plan is based on Intel E810 series ethernet cards.
> +when priority is not active, flows are created on fdir then switch/ACL.
> +when priority is active, flows are identified into 2 category:
> +High priority as permission stage that maps to switch/ACL, Low priority
> +as distribution stage that maps to fdir, a no destination high priority
> +rule is not acceptable, since it may be overwritten by a low priority rule due
> to cvl FXP behavior.
> +
> +Note: Since these tests are focus on priority, the patterns in tests are
> examples.
