5.9.3 ToS Mapping
ToS is an acronym for Type of Service. It is implemented as the IPv4 ToS priority control. It is
fully decoded to determine the priority from the 6-bit ToS field in the IP header. The most
significant 6 bits of the ToS field are fully decoded into 64 possibilities, and the singular code
that results is compared against the corresponding bit in the IPv4 ToS priority control bit (0~63).
