Visual Echo, could you please test the latest upstream kernel available
from the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

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

Status in iproute2 package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrading an Ubuntu server from Lucid -> Precise -> Trusty the command:
  tc -s class show dev eth0
  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:

  $ dpkg -s iproute2

  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
  2015 x86_64 x86_64 x86_64 GNU/Linux

  Thank you!
