Current the ASO age action was supported in the non-root table,
and the counter based age action was be used in the root table.

The FDB table skips group 0 on MLX5 PMD by adding implicit rule

[dpdk-dev] [PATCH 2/2] net/mlx5: fix ASO age null context issue

[Jiawei Wang]

The flow context in the rte_flow_action_age structure was set by user,
and reported by the MLX5 PMD while calling rte_flow_get_aged_flow API.
If the flow context was NULL while create ASO age action, while flow
aged, the PMD report the NULL context to user.

This patch adds the checking if context is NULL then return rte_flow
pointer to user, otherwise return the original flow context.

[dpdk-dev] [PATCH v2 2/2] net/mlx5: fix default context in flow age action

[Jiawei Wang]

One of the user parameters for the flow AGE action is the
action context. This context should be provided back to the
user when the action is aged-out.
While this context is NULL, a default value should be provided
by the PMD: the rte_flow pointer in case of rte_flow_create API
and the action pointer in case of the rte_flow_action_handle API.

The default for rte_flow_action_handle was set correctly,
while in case of rte_flow_create it wrongly remained NULL.

This patch set the default value for rte_flow_create case to be
the rte_flow pointer.

and the counter based age action was be used in the root table.

The FDB table skips group 0 on MLX5 PMD by adding implicit rule
that jump to non-root table, but PMD code use the original group
value for checking.

This patch adds the transfer checking for ASO age action.

[dpdk-dev] [PATCH v3 2/2] net/mlx5: fix default context in flow age action

[Jiawei Wang]

One of the user parameters for the flow AGE action is the
action context. This context should be provided back to the
user when the action is aged-out.
While this context is NULL, a default value should be provided
by the PMD: the rte_flow pointer in case of rte_flow_create API
and the action pointer in case of the rte_flow_action_handle API.

The default for rte_flow_action_handle was set correctly,
while in case of rte_flow_create it wrongly remained NULL.

This patch set the default value for rte_flow_create case to be
the rte_flow pointer.
