When replacing a child qdisc from mqprio, tc_modify_qdisc() must fetch the netdev_queue pointer that the current child qdisc is associated with before creating the new qdisc. Currently, when using mqprio as root qdisc, the kernel will end up getting the queue #0 pointer from the mqprio (root qdisc), which leaves any new child qdisc with a possibly wrong netdev_queue pointer. Implementing the Qdisc_class_ops select_queue() on mqprio fixes this issue and avoid an inconsistent state when child qdiscs are replaced.

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.
