 TOS priority: The system provides 0~63 TOS priority level. Each level has 4 types
of priority—High, Middle, Low, and Lowest. The default value is ‘Lowest’ priority for each
level. When the IP packet is received, the system will check the TOS level value in the
IP packet that has received. For example, the user sets the TOS level 25 as high, the
system will check the TOS value of the received IP packet. If the TOS value of received
IP packet is 25 (priority = high), and then the packet priority will have highest priority.
