With this addition, it becomes possible to simulate interference and control transmission behavior in IEEE 802.15.4 networks using a userspace backend.

that is already being possible by using raw sockets, what is the
difference here? Depending on your use case it might depend on what
kind of mac instance "wpan_dev" is created on top of your phy. If you
just want to have bare phy access you are looking into monitor wpan
dev types and using AF_PACKET raw sockets. I already connected user
space stacks (only for development) with it.

If you want to have ARET/AACK support, the answer is more complicated.
