[ Upstream commit 06bc6f6ed4ae0246a5e52094d1be90906a1361c7 ] When we mark a TID as no longer having a queue, there's no guarantee the TX path isn't using this txq_id right now, having accessed it just before we reset the value. To fix this, add synchronize_net() when we change the TIDs from having a queue to not having one, so that we can then be sure that the TX path is no longer accessing that queue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
