-Subject: [PATCH] dpaa2-eth: Add support for Rx traffic classes
-
-The firmware reserves for each DPNI a number of RX frame queues
-equal to the number of configured flows x number of configured
-traffic classes.
-
-Current driver configuration directs all incoming traffic to
-FQs corresponding to TC0, leaving all other priority levels unused.
-
-Start adding support for multiple ingress traffic classes, by
-configuring the FQs associated with all priority levels, not just
-TC0. All settings that are per-TC, such as those related to
-hashing and flow steering, are also updated.
-
