Is there a different fix that went in in 3.10.2 or 3.11-rc? 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. Larry
