Traffic Shaping under kernel 4.4

[David Nix]

Hi All,

I am seeking information whether anyone come across this issue before. Basically traffic shaping stopped working as I started to use kernel 4.4.19 The rules seem to be in place but packets do not get queued at all.

Hi Brad,

Can you please explain what sort of logs are you missing?

I am not able to run this command unfortunately.

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi Joseph,

I've tested the kernel ,but no luck. I am supposed to get 10M but I am getting much more than that.
