| 4 | Subject: [PATCH] dpaa2-eth: Trim debugfs FQ stats |
| 5 | |
| 6 | With the addition of multiple traffic classes support, the number |
| 7 | of available frame queues grew significantly, overly inflating the |
| 8 | debugfs FQ statistics entry. Update it to only show the queues |
| 9 | which are actually in use (i.e. have a non-zero frame counter). |
