[Thomas Petazzoni]

Dear Tom Sparks,

Thanks for this contribution. Vicente already made a review with some
comments, I'll add some more comments in this review.

As Vincente said, each package should be added in a separate patch.
Each patch should have a title like this:

	<package>: new package

so, your series should have three patches:

	ibrcommon: new package
	ibrdtn: new package
	ibrdtnd: new package

And indeed each patch should add the package in package/Config.in to
make it visible in menuconfig.

Please read the Buildroot manual about adding a comment mentioning the
toolchain dependencies, especially "17.2.4. Dependencies on target and
toolchain options".

Not needed, since it is the default value.

Too many unneeded empty lines.

Too many unneeded new lines. Also, you're missing the Config.in comment
about toolchain dependencies.

Unneeded, this is the default.

Same comments for the rest of the patch. Other than those basic
comments, it seems good.

Did you check if your packages work on noMMU platforms? For example, if
they use fork(), they will not work on noMMU platforms, and so you need
to add a BR2_USE_MMU dependency.

Thanks!
