[PATCH net-next 0/4] mlx5: Support setting a parent for a devlink rate node

[PATCH net-next 0/4] mlx5: Support setting a parent for a devlink rate node

[Tariq Toukan]

Hi,

This series by Carolina adds mlx5 support for the setting of a parent to
devlink rate nodes.

By introducing a hierarchical level to scheduling nodes, these changes
allow for more granular control over bandwidth allocation and isolation
of Virtual Functions.

Function renaming for parent setting on leafs:
- net/mlx5: Rename devlink rate parent set function for leaf nodes

Add support for hierarchy level tracking:
- net/mlx5: Introduce hierarchy level tracking on scheduling nodes
- net/mlx5: Preserve rate settings when creating a rate node

Support setting parent for rate nodes:
- net/mlx5: Add support for setting parent of nodes

Regards,
Tariq

[PATCH net-next 1/4] net/mlx5: Rename devlink rate parent set function for leaf nodes

[Tariq Toukan]

From: Carolina Jubran <cjubran@nvidia.com>

Rename `mlx5_esw_devlink_rate_parent_set()` to
`mlx5_esw_devlink_rate_leaf_parent_set()` to distinguish setting a
parent for leafs from nodes, which is not yet supported.

[PATCH net-next 2/4] net/mlx5: Introduce hierarchy level tracking on scheduling nodes

[Tariq Toukan]

From: Carolina Jubran <cjubran@nvidia.com>

Add a `level` field to `mlx5_esw_sched_node` to track the hierarchy
depth of each scheduling node. This allows enforcement of the
scheduling depth constraints based on `log_esw_max_sched_depth`.

Modify `esw_qos_node_set_parent()` and `__esw_qos_alloc_node()` to
correctly assign hierarchy levels. Ensure that nodes inherit their
parent’s level incrementally.

[PATCH net-next 3/4] net/mlx5: Preserve rate settings when creating a rate node

[Tariq Toukan]

From: Carolina Jubran <cjubran@nvidia.com>

Modify `esw_qos_create_node_sched_elem()` to receive max_rate and
bw_share values while maintaining the previous configuration.

This change is essential for the upcoming patch that will modify rate
nodes and requires the existing settings to be preserved unless
explicitly changed.

[PATCH net-next 4/4] net/mlx5: Add support for setting parent of nodes

[Tariq Toukan]

From: Carolina Jubran <cjubran@nvidia.com>

Introduce `mlx5_esw_devlink_rate_node_parent_set()` to allow assigning
a parent to scheduling nodes.
Implement `mlx5_esw_qos_node_update_parent()` and
`mlx5_esw_qos_node_validate_set_parent()` to enforce constraints on
node reassignment.

Don't allow reassignment of nodes with active rate objects.

Update `esw_qos_node_set_parent()` to handle cases where
the parent is NULL. A NULL parent indicates that the scheduling element
is attached to the root scheduling element, and since only rate nodes
can be connected to the root, this update is now necessary.

Minor nit for a possible small follow-up: it could be possibly useful to
add to the extact the current and max level.
