We can't just pull one file and add it to rsb, this will make it almost
impossible to track with the upstream. It would be better to add the whole
package. Did you find the official source?

To add the package, we need to add a separate set of cfg for netinet and
then add a reference in the ptpd cfg so that it builds before ptpd. qemu or
qemu-couverture can be examples of how to add a github repository to rsb
and build it. Please have a look at them and feel free to ask if you don't
understand something (maybe in a separate thread :) )

Also, please post the source of the package that you want to add, so that
there's no objection with the source later.


Chris commented about possible errors in the script, you might have to
follow up with him to fix the issue so that you don't face any problems
later.

Best regards,
Vijay

Or there's way to add just this file. I have tried finding netinet tar
