Loosely based on [the original ping] and [netutil]'s ping New features (compared to old RIOT version): - non-positional parameters - Better duplicate detection (addresses #9387) - Better asynchronous behavior - Potential for future move to `sock_ip` - (Optional) DNS-support - Multithreading-safe (in case shell-command handler gets called from multiple threads) [the original ping]: http://ftp.arl.army.mil/~mike/ping.html [netutil]: https://www.gnu.org/software/inetutils/
