Hi Google,

While playing with RPS, I needed to read stats from 
/proc/net/softnet_stat and the tools I could find [1] and [2] was not
very good.

I lack of better, I coded up my own tool softnet_stat.pl here:
 https://github.com/netoptimizer/network-testing/blob/master/bin/softnet_stat.pl

The output format/columns in /proc/net/softnet_stat is undocumented,
plus values are printed in hex.  E.g. to decode the columns you need to
read kernel function kernel softnet_seq_show() in
kernel/net/core/net-procfs.c.

To make things easier I wrote this small perl script for get
so human readable statistics from /proc/net/softnet_stat.
