enabled ToS and CoS priority. The value range is 0-7. The
higher the value, the higher the priority.
Description:
By default, switch would use port priority in place of the 802.1p
priority the port comes with when receiving message to control
the quality of service the messages deserve.
When the ToS and CoS are not enabled, queuing and scheduling are in the order of port
priority.
When the ToS or CoS are enabled, queuing and scheduling according to ToS or CoS
instead of considering port priority.
If the ToS and CoS are enabled at the same time, queuing according to ToS priority.
When the ToS values are the same, queuing according to CoS priority.
