When the QoS Map Set feature is enabled,
the AP maps the DSCP of each packet to the user priority TID automatically before
sending the packet to the wireless client. Beginning with release 7.0, SmartCast
supports all 64 DSCP values and all 8 TID values (0-8), ensuring application of the
appropriate access category queue (best effort, background, video, or voice) to each
packet. The following table depicts how SmartCast handles DSCP to TID mapping.
