The IPv4 TOS priority control registers implement a fully decoded 64 bit DSCP (Differentiated Services Code Point)
register used to determine 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 DSCP register. If the register bit is a 1, the priority is high; if it is a 0, the priority is low.
