I applied this to IWL net dev-queue, but I had some conflicts when
applying which I resolved manually. I would appreciate review of the
contents as committed:

https://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue.git/commit/?h=dev-queue&id=b0bdaaffc27a79460a8053c2808fc54e4cbdd576

Thanks,
