Subject: [PATCH net-next 0/2] net: ethernet: ti: am65-cpsw: enable DSCP to
 priority map for RX

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-2004. Priority Code Point (PCP) 2 is higher priority than
PCP 0 (Best Effort). PCP 1 (Background) is lower priority than
PCP 0 (Best Effort).
