Subject: dpaa2-eth: trim debugfs FQ stats
Git-commit: 0da1e28f97352fb8aadde4d66774373bedd50408
Patch-mainline: v5.9-rc1
References: jsc#SLE-12251
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).
