Public bug reported:
Recently I noticed the gnome-system-monitor was reporting unreasonably
high speeds for transfers to/from my NAS, and it seems the fault is in
(or also applies to) ifconfig. For example:
ifconfig eth1; dd if=/dev/zero of=/nfs/thecus/data/temp.dat bs=1M count=100;
ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:1b:21:2f:ae:37

Instead of 100MB being reported, ifconfig is reporting 1288MB!
