Major fping detection, introduced in 1.8.4, helps a lot - but there are some improvements still possible.
1. currently each pinger process detects fping capabilities separately - might be more efficient if server (or proxy) did that one upon startup and then just pass the result to all pinger processes.
2. currently there is no information with debuglevel 3 about detection status - would be very helpful if zabbix daemon could print in the logfile the detection status.
