Advanced Control Registers
The IPv4/IPv6 TOS Priority Control Registers implement a fully decoded, 128-bit DSCP (Differentiated Services
Code Point) register set that is used to determine priority from the ToS (Type of Service) 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 bits in the DSCP register to determine the priority.

Description
1 = link speed is 100Mbps
0 = link speed is 10Mbps
1 = link duplex is full
0 = link duplex is half
= 1, Far-end fault status detected
= 0, no Far-end fault status detected
