Register 144 (0x90): TOS Priority Control Register 0
The Ipv4/Ipv6 TOS priority control registers implement a fully decoded 64 bit differentiated services code point (DSCP) 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 mapped to the value in the corresponding bit in the DSCP register.
