Sorry I don't understand what the change is doing.
Was there an issue?
In the title, please avoid "tc ov" which is meaningless
for most of readers I guess.

Hi Thomas,
This is a fix for oversubscription threshold value of traffic class which is computed later. We will re-spin the patch by mentioning "fix" in the message and title.
