Hi,

i added this package to my local packages and wanted to get some comment on

Are there any obvious problems/mistakes/things i should do differently?
What would i need to do to get this commited?

Thank you
Jens

Alphabetical order, please. batctl should be after bandwidthd.

Why? fork() does not seem to be used anywhere in the source tree.

libnl depends on threads, so you must propagate the dependency, like so:

    depends on BR2_TOOLCHAIN_HAS_THREADS # libnl
    select BR2_PACKAGE_LIBNL

Indentation for options should be jsut one tab; indentation for the help
text should be one tab + two spaces.

As for the help text, we usually like to have the first few sentences
that upstream provides, and a direct link to the upstream homepage of
the project. Your pointer is about the whole B.A.T.M.A.N. project; I
found this to be better suited, no?

    Batctl is the configuration and debugging tool for batman-adv.

Your mail client wraps lines, so we can't apply the patch. Please use
git-send-email (or fix your mail client to not line-wrap).

Ditto, line-wrapped.

> +BATCTL_LICENSE = GPLv2+

There is no 'or later' clause anywhere in the source tree, so this
should be just "GPLv2".

And there is indeed no license file. :-/

> +BATCTL_DEPENDENCIES += libnl
> +BATCTL_CFLAGS += "-I$(STAGING_DIR)/usr/include/libnl3

You're not using BATCTL_CFLAGS, so just remove that line.

DBM_INCLUDES does not seem to be used in the source tree. Care to see if
it really is needed?

Indentation for _CMDS definitions is one tab.

> +define BATCTL_INSTALL_TARGET_CMDS

Ditto, indent by one tab.

Well, all the above are pretty minor issues. :-)
Care to have a look at them and respin your patch?

Thanks!
