Nothing staggering in my review but a few points I'd like to discuss.

Implement the common parts of the RX pipeline. At this point, about 90% of the work is done. All that is left is to add the basic public API wrappers for subscriptions and RPC-services. For details about the implementation of the RX pipeline refer to the line that says "Internally, the RX pipeline is arranged as follows".
Slightly refactor the code added earlier to uphold orthogonality and avoid unnecessary duplication.
Trivial renamings to keep names shorter, e.g.:
UdpardConstPayload->UdpardPayload(const implied by default; there's alsoUdpardMutablePayload)UdpardPayloadFragmentHandle->UdpardFragmentEstablish an internal convention that functions named "Destroy" deallocate the passed memory while "Free" only deallocate the memory of the associated resources. This is not API-visible.
Remove the
port_idfield fromUdpardRxPortbecause it is not needed.After this is merged, the remaining task is to simply implement the public RX pipeline functions on top of:
rxPortInitrxPortAcceptFramerxPortFreeThe test coverage is supposed to be full but llvm-cov slightly misreports it.
