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
