‗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.
