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).
|
||
