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>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
