First 5 patches are preparations for the last one.
Motivation:
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.
Solution:
Allow user to pass devlink handle (and possibly other attributes)
alongside the dump command and dump only objects which are matching
the selection.
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
Jiri Pirko (6):
devlink: move DL_OPT_SB into required options
devlink: make parsing of handle non-destructive to argv
devlink: implement command line args dry parsing
devlink: return -ENOENT if argument is missing
mnl_utils: introduce a helper to check if dump policy exists for
command
devlink: implement dump selector for devlink objects show commands

This is basically a cosmetic change. The SB index is not required to be
passed by user and implicitly index 0 is used. This is ensured by
special treating at the end of dl_argv_parse(). Move this option from
optional to required options.

Currently, handle parsing is destructive as the "\0" string ends are
being put in certain positions during parsing. That prevents it from
being used repeatedly. This is problematic with the follow-up patch
implementing dry-parsing. Fix by making a copy of handle argv during
parsing.

dl_argv_dry_parse() which allows to do dry parsing of command line

From: Jiri Pirko <jiri@nvidia.com>
Introduce a new helper dl_argv_parse_with_selector() to be used
by show() functions instead of dl_argv().
Implement it to check if all needed options got get commands are
specified. In case they are not, ask kernel for dump passing only
the options (attributes) that are present, creating sort of partial
key to instruct kernel to do partial dump.
