This patch set adds support for Rx traffic classes on DPAA2 Ethernet
devices.

The first two patches make the necessary changes so that multiple
traffic classes are configured and their statistics are displayed in the
debugfs. The third patch adds a static distribution to said traffic
classes based on the VLAN PCP field.

The last patches add support for the congestion group taildrop mechanism
that allows us to control the number of frames that can accumulate on a
group of Rx frame queues belonging to the same traffic class.

How is this configured from the user perspective? I looked through the
patches and I see no information on how the input is taken from the
user.
