Series net: ethernet: ti: am65-cpsw: Add multi queue RX support | expand

Commit Message

Roger Quadros July 3, 2024, 1:51 p.m. UTC 
Now that we support multiple RX queues, enable default priority
to flow mapping so that higher priority packets come on higher
channels (flows).

The Classifier checks for PCP/DSCP priority in the packet and
routes them to the appropriate flow.
