The fq_codel qdisc currently always regenerates the skb flow hash. This wastes some cycles and prevents flow seperation in cases where the traffic has been encrypted and can no longer be understood by the flow dissector. Change it to use the prexisting flow hash if one exists, and only regenerate if necessary.

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.
