Capstats: fast NIC statistics reporting tool

Just came across a nice tool to display NIC statistics, it is called capstats. Capstats is much less CPU intensive that iptraf, so it can be run along with hping3 to monitor its performance.

Example from capstats's website:
>capstats -i nve0 -I 1
1186620936.890567 pkts=12747 kpps=12.6 kbytes=10807 mbps=87.5 nic_pkts=12822 nic_drops=0 u=960 t=11705 i=58 o=24 nonip=0
1186620937.901490 pkts=13558 kpps=13.4 kbytes=11329 mbps=91.8 nic_pkts=13613 nic_drops=0 u=1795 t=24339 i=119 o=52 nonip=0
