There are now stubs for some allocation functions, which at least make the analysis sound and don't leave important functions uncalled. Nevertheless, even with symbolic locks we find almost everything to be racing because these net drivers heavily use data and mutexes stored deep in dynamically allocated structs. Our char drivers are much easier because they use global arrays. |

Goblint's analysis for all of them is unsound because the unknown
register_netdevdoesn't spawn all the operation functions since they've been written through an unknown pointer.
