you removed the shell, and doing so you also removed the main loop. So
basically your program hits return 0 and terminates - which likely happens very
fast after reboot. With this the RIOT-Kernel, network stack and everything
stops working, so no logic remains to answer any pings or so.
I don't know what your goal is, but if you look at the microcoap example here
 (line 44-47), you'll see it does the same: no shell and it has this
_netif_config line, too. But instead of hitting return 0 it enters
`microcoap_server_loop()` which keeps running forever.
