Instead of using a custom offloading interface, users can use `NET_SOCKET_REGISTER` macro to register custom socket API provider. This solution removes a limitation, that only one offloaded interface can be registered and that it cannot be used together with native IP stack. The only exception remainig are DNS releated operations - `getaddrinfo`/`freeaddrinfo`, which, when offloaded, have to be registered specifically.
