I'm terribly sorry but I think you have confused with a Linux Kernel 
developer.

I run a site which uses Ubuntu, I found a bug, and I reported it.  Try 
http://pipes.mdve.net if you'd like to buy a wooden smoking pipe.

I'm a carpenter.  Besides pushing work on other people, what is it that 
*you* do?

Title:
  tc class statistics rates are all zero after upgrade to Trusty

  After upgrading an Ubuntu server from Lucid -> Precise -> Trusty the command:

  no longer shows rates for my classification bands. This worked in Lucid, but not sure if something changed, or if I need to set some system configuration to make it work again. My current non-working version is:

  Description: networking and traffic control tools
   The iproute2 suite is a collection of utilities for networking and
   traffic control.
   .
   These tools communicate with the Linux kernel via the (rt)netlink
   interface, providing advanced features not available through the
   legacy net-tools commands 'ifconfig' and 'route'.

  Here is the current output of the command, note that 'rate 0bit 0pps'
  is common to all classes, in Lucid this would produce non-zero values
  for active traffic:

  Did something change upstream to make the rates unavailable? Do I need
  to set some config to enable collection? Running the command as root
  does not make a difference. My kernel is:

  Linux srvr1 3.13.0-46-generic #75-Ubuntu SMP Tue Feb 10 15:24:04 UTC
