+Subject: [PATCH] dpaa2-eth: Trim debugfs FQ stats
+
+With the addition of multiple traffic classes support, the number
+of available frame queues grew significantly, overly inflating the
+debugfs FQ statistics entry. Update it to only show the queues
+which are actually in use (i.e. have a non-zero frame counter).
+
