Can you fill in more details about what the user visible problem is?
Judging by the fact that you haven't tagged the patch as 
[PATCH net-next] after my previous explanation you do think this 
is a fix. But "Add xyz support" sounds like a feature, not a fix.

I don't think you were modifying this code, so no need to clean it up
in this commit. It's unrelated to the change you're making now.

Here, tho, you are changing the code, and yet you haven't done what 
I asked.
