devlink: introduce possibility to expose info about nested devlinks In mlx5, there is a devlink instance created for PCI device. Also, one separate devlink instance is created for auxiliary device that represents the netdev of uplink port. This relation is currently invisible to the devlink user. Benefit from the rel infrastructure and allow for nested devlink instance to set the relationship for the nested-in devlink instance. Note that there may be many nested instances, therefore use xarray to hold the list of rel_indexes for individual nested instances. Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

devlink: introduce object and nested devlink relationship infra It is a bit tricky to maintain relationship between devlink objects and nested devlink instances due to following aspects: 1) Locking. It is necessary to lock the devlink instance that contains the object first, only after that to lock the nested instance. 2) Lifetimes. Objects (e.g devlink port) may be removed before the nested devlink instance. 3) Notifications. If nested instance changes (e.g. gets registered/unregistered) the nested-in object needs to send appropriate notifications. Resolve this by introducing an xarray that holds 1:1 relationships between devlink object and related nested devlink instance. Use that xarray index to get the object/nested devlink instance on the other side. Provide necessary helpers: devlink_rel_nested_in_add/clear() to add and clear the relationship. devlink_rel_nested_in_notify() to call the nested-in object to send notifications during nested instance register/unregister/netns change. devlink_rel_devlink_handle_put() to be used by nested-in object fill function to fill the nested handle.
