Bank 39 MAC Address Register 2 (0x02): MACAR2
This register contains the MAC address for the switch function. This MAC address is used for sending PAUSE frame.
Bank 39 MAC Address Register 3 (0x04): MACAR3
This register contains the MAC address for the switch function. This MAC address is used for sending PAUSE frame.
Bank 40 TOS Priority Control Register 1 (0x00): TOSR1
The Ipv4/Ipv6 ToS priority control registers implement a fully decoded,128-bit DSCP (Differentiated Services Code Point)
register used to determine priority from the 6-bit 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.
This register contains the ToS priority control for the switch function.
