Hi! This was my mistake, very sorry about it, re-opening this PR now. What happened is the following: I was switching the base branch for this repository https://github.com/wittra/contiki-ng from develop to wittra. But accidentally, I made the change on the wrong repo (this repo) and instead of switching the base branch I renamed it. And somehow github deleted develop and closed all PRs... Many apologies for this mishap 🙏; I haven't contributed in a while.. but now at least everybody got some notification from me :p |

As per RFC 4944, a fragment header may also precede an unfragmented packet. Currently, such fragments end up in the reassembly buffer and are not passed on to uip. To fix this, I delayed the creation of reassembly contexts until we know that further fragments are needed.
