[PATCH iproute2-next 0/3] minor improvements to makefile, devlink

[Przemek Kitszel]

Three minor improvements: better error messages from devlink app,
fix to one example in the man page of devlink-resource,
and better build experience for single-app focused devs.

Przemek Kitszel (3):
  man: devlink-resource: add missing words in the example
  devlink: print missing params even if an unknown one is present
  Makefile: support building from subdirectories

[PATCH iproute2-next 1/3] man: devlink-resource: add missing words in the example

[Przemek Kitszel]

Add missing "size" and "path" words in the example, as the current example
is incorrect and will be rejected by the command.

The keywords were missing from very inception of devlink-resource man page

[PATCH iproute2-next 2/3] devlink: print missing params even if an unknown one is present

[Przemek Kitszel]

Print all of the missing parameters, also in the presence of unknown ones.

Take for example a correct command:
    $ devlink resource set pci/0000:01:00.0 path /kvd/linear size 98304
And remove the "size" keyword:
    $ devlink resource set pci/0000:01:00.0 path /kvd/linear 98304
That yields output:
    Resource size expected.
    Unknown option "98304"

Prior to the patch only the last line of output was present. And if user
would forgot also the "path" keyword, there will be additional line:
    Resource path expected.
in the stderr.

[PATCH iproute2-next 3/3] Makefile: support building from subdirectories

[Przemek Kitszel]

Support building also from subdirectories, like: `make -C devlink` or
`cd devlink; make`.

Extract common defines and include flags to a new file (common.mk) which
will be included from subdir makefiles via the generated config.mk file.

Note that the current, toplevel-issued, `make` still works as before.
Note that `./configure && make` is still required once after the fresh
checkout.

Not sure if this really needed, it impacts more than devlink.

[1]
This last "Note" could be fixed too to have proper dependencies
(in example of devlink, lib should be build first for example), and it
works now only thanks to serialized builds in terms of SUBDIRS in top
level Makefile.

devlink is just an example here

This patch makes my development easier but it is not fixing [1]
above, so it's just a shortcut. You could drop this patch, let
me know if you will be interested in extending it to have [1] fixed.

That is a very disruptive requirement - e.g., someone running git bisect.

Even after a configure, I get build failures:
