The reason that patch is not in mainline is that it takes time. If you want to 
have it, you can get the official patch from 
http://marc.info/?l=linux-wireless&m=137242880222442&w=2, or you need to 
implement kernels from the wireless-testing git tree, where it was added on June 
28 as commit bcfb879. My original patch included the following note for John 
Linville:

"Ideally, this patch should be pushed to the 3.10 stream; however, at this late 
time that is not possible. Please push it for 3.11 and the Cc to stable will get 
it into 3.10.X."

As you see, it was marked with a Cc for Stable, and it will be propagated to 
3.10 when it gets incorporated by Linus. I think I have done all that I can do 
for now.

If you want to lobby Linus to get stuff accepted faster, that is your 
prerogative; however, I could not recommend that action, and I certainly will 
never do anything like that.
