Configure DSCP to Priority mapping registers so that IP precedence field (top 3 bits of DSCP) map it to one of the 8 priority queues for RX traffic. Also update Priority to Thread maping to be compliant with IEEE802.1Q-2014. Priority Code Point (PCP) 2 is higher priority than PCP 0 (Best Effort). PCP 1 (Background) is lower priority than PCP 0 (Best Effort).
