| 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). |
