      Specifies MAC address 3. This value has to be same as MARL in Bank2.
      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.
      Bit
      Default
