[mini] /usr/src # time ping -f -c2 10.0.2.1
PING 10.0.2.1 (10.0.2.1): 56 data bytes
.
--- 10.0.2.1 ping statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 9.752/9.934/10.115/0.182 ms

real    0m0.024s
user    0m0.008s
sys     0m0.001s

however, 200 results in packet loss:

[mini] /usr/src # time ping -f -c200 10.0.2.1
PING 10.0.2.1 (10.0.2.1): 56 data bytes
..............
--- 10.0.2.1 ping statistics ---
200 packets transmitted, 187 packets received, 6.5% packet loss
round-trip min/avg/max/stddev = 3.782/10.161/15.065/2.029 ms
