[PATCH net-next v2 0/2] net: ethernet: ti: am65-cpsw: enable DSCP to priority map for RX

Posted by Roger Quadros 2 weeks, 2 days ago

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).
