Subject: [PATCH 082/189] net/hns3: fix flow counter value
|
|
|
|
User could create flow rules with specified counter by the action of
|
|
RTE_FLOW_ACTION_TYPE_COUNT, but the counter may retain the original
|
|
value when create.
|
|
|
|
This patch fix the bug by read the counter when creating the rule
|
|
because the counter is read-clear.
|
|
|
|
Fixes: fcba820d9b9e ("net/hns3: support flow director")
