This patch sets up the infrastructure for offloading TCs and queue configurations to the hardware by creating HW channels(VSI). A new channel is created for each of the traffic class configuration offloaded via mqprio framework except for the first TC (TC0). TC0 for the main VSI is also reconfigured as per user provided queue parameters. Queue counts that are not power-of-2 are handled by reconfiguring RSS by reprogramming LUTs using the queue count value. This patch also handles configuring the TX rings for the channels, setting up the RX queue map for channel. Also, the channels so created are removed and all the queue configuration is set to default when the qdisc is detached from the root of the device.

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.
