A maximum of 16 port ranges are supported for each hardware device (ASIC).
Up to 8 policies, composed of up to 128 rules each can be added for each
hardware device (ASIC).
Using unrestricted role for ports, traffic will be prioritized based on 802.1p
priority, allowing filters to be configured based on specific application needs.
For example, assign all packets marked with DSCP EF priority, such as with
VoIP, to the highest priority queue.
