For flow split to several subflows, the match items maybe in the prefix
flow, and the actions are split to the suffix flow.
In this case, for the actions need the user defined match item will not
create correctly.
Copy the item layers flags to the suffix flow from prefix flow to fix
the issue.
This patch series should be applied after:

Unfortunately, hash_fields will only be generated if flow has RSS action. So it means the prefix flow won't generate the hash_fields as the RSS action has been split to the suffix flow. Copy the layer flags from prefix subflow to suffix subflow to help the suffix subflow to generate the correct hash_fields itself.

Unfortunately, hash_fields will only be generated if flow has RSS action. So it means the prefix flow won't generate the hash_fields as the RSS action has been split to the suffix flow. Copy the layer flags from prefix subflow to suffix subflow to help the suffix subflow to generate the correct hash_fields itself.

Currently, all the user defined items are matched in the prefix flow. Flow id tag match item is the only item added to the meter suffix subflow. Some of the remaining actions to be applied in the suffix subflow require more information in the match item, or the suffix subflow will not be created successfully.

Unfortunately, hash_fields will only be generated if flow has RSS action. So it means the prefix flow won't generate the hash_fields as the RSS action has been split to the suffix flow. Copy the layer flags from prefix subflow to suffix subflow to help the suffix subflow to generate the correct hash_fields itself.
