Packet size doesn't display over 4096 bytes

[Shourai]

When running fping with a packet size of over 4096 bytes, it doesn't
correctly display the size and always defaults to displaying 4096.

So when I run fping -c 10 -M -b 9000, to check jumbo frames.
[0], 4090 bytes, 0.03 ms (0.03 avg, 0% loss)

However if I run a tcpdump I do see that the package size does go over 4096 bytes.
ICMP echo request, id 11483, seq 0, length 9008

fixed in a136764 (to be released with fping 5.0)
