 OK it's EWMA calc in kernel. For another purpose I tried another approach 
 to satisfy some users that wanted Cisco like average stats on our routers. 
 User app/daemon reads stats via netlink and does average calc. looks like:
 ifstat2  eth*
             RX --------------------------   TX -------------------------
eth0          389.4 M bit/s       40 k pps     20.7 M bit/s       40 k pps 
eth1            3.1 k bit/s        4   pps    686.5 k bit/s       65   pps 
eth2           19.3 M bit/s       37 k pps    363.5 M bit/s       38 k pps 

As usual most code is honestly stolen from Alexey. :-)
