Well, netapi right now is
int ng_netapi_send(kernel_pid_t pid, ng_pktsnip_t *pkt);
If we omit the messaging, and the pktbuf dependency, it is not "netapi"
Also, the default stack's whole design is based on threads passing
messages containing pktsnips. Changing that would change the whole concept.
Applications now should be written in a network stack agnostic way.
So if the stack implementor decides to go for the benefits of having
clear module seperation and flexibility through using messages and
threads, that still shouldn't force our application interfaces to that
