FreeBSD bsdrp1.orange.bsdrp.net 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255918M: Sat Oct 26 22:41:39 CEST 2013 root@orange.bsdrp.net:/usr/obj/BSDRP.amd64/usr/local/BSDRP/BSDRP/FreeBSD/src/sys/amd64 amd64
>Description:
1K packets = 1000 packets and not 1024 packets.
But netstat "-h" option convert 1024 packets to 1k packets.
In usr.bin/netstat/if.c, function show_stat() should call humanize_number() with the flag HN_DIVISOR_1000 for the packet counters.
>How-To-Repeat:
Here is the netstat output without and with the "h" option during receiving the same network load:
[root@bsdrp2]~# netstat -iw 1
