Subject: [PATCH 098/122] ethdev: fix port close in secondary process
|
|
|
|
Secondary process needs to close device to release process private
|
|
resources. But secondary process should not be obliged to wait for
|
|
device stop before closing ethdev.
|
|
|
|
Fixes: febc855b358e ("ethdev: forbid closing started device")
