Subject: [PATCH] soc: fsl: dpio: Fix order restoration API for QBMan 5.0
|
|
|
|
The mechanism for indicating to HW that a frame was dropped
|
|
when performing HW order restoration changed in QBMan 5.0 to
|
|
use a management command instead of a special enqueue command.
|
|
This patch implements that change when running on a QBMan 5.0
|
|
and above device.
