I have been looking for such a feature too.
My Application; Bandwidth tester (also as a support app for an UDP file
transfer utility)
The reason i want DF bit removed? I want to be able to generate my own
fragments or let the routers generate the fragments.
I also want to be able to receive bad UDP packets to gather statistics.
This would be userland applications.
