devlink: split out netlink code Move out the netlink glue into a separate file. Leave the ops in the old file because we'd have to export a ton of functions. Going forward we should switch to split ops which will let us to put the new ops in the netlink.c file. Pure code move, no functional changes.

devlink: add by-instance dump infra Most dumpit implementations walk the devlink instances. This requires careful lock taking and reference dropping. Factor the loop out and provide just a callback to handle a single instance dump. Convert one user as an example, other users converted in the next change. Slightly inspired by ethtool netlink code.

Allow user to pass devlink handle attributes alongside the dump command and dump only objects which are under selected devlink instance.

devlink: remove devlink_dump_for_each_instance_get() helper devlink_dump_for_each_instance_get() is currently called from a single place in netlink.c. As there is no need to use this helper anywhere else in the future, remove it and call devlinks_xa_find_get() directly from while loop in devlink_nl_instance_iter_dump(). Also remove redundant idx clear on loop end as it is already done in devlink_nl_instance_iter_dump().

devlink: add by-instance dump infra Most dumpit implementations walk the devlink instances. This requires careful lock taking and reference dropping. Factor the loop out and provide just a callback to handle a single instance dump. Convert one user as an example, other users converted in the next change. Slightly inspired by ethtool netlink code.

devlink: allow user to narrow per-instance dumps by passing handle attrs For SFs, one devlink instance per SF is created. There might be thousands of these on a single host. When a user needs to know port handle for specific SF, he needs to dump all devlink ports on the host which does not scale good. Allow user to pass devlink handle attributes alongside the dump command and dump only objects which are under selected devlink instance. Example: $ devlink port show auxiliary/mlx5_core.eth.0/65535: type eth netdev eth2 flavour physical port 0 splittable false auxiliary/mlx5_core.eth.1/131071: type eth netdev eth3 flavour physical port 1 splittable false $ devlink port show auxiliary/mlx5_core.eth.0 auxiliary/mlx5_core.eth.0/65535: type eth netdev eth2 flavour physical port 0 splittable false $ devlink port show auxiliary/mlx5_core.eth.1 auxiliary/mlx5_core.eth.1/131071: type eth netdev eth3 flavour physical port 1 splittable false Signed-off-by: Jiri Pirko <jiri@nvidia.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Link: https://lore.kernel.org/r/20230811155714.1736405-11-jiri@resnulli.us Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: split out netlink code Move out the netlink glue into a separate file. Leave the ops in the old file because we'd have to export a ton of functions. Going forward we should switch to split ops which will let us to put the new ops in the netlink.c file. Pure code move, no functional changes.
