[ Upstream commit 01634047bf0d5c2d9b7d8095bb4de1663dbeedeb ] fq qdisc requires tstamp to be cleared in the forwarding path. Now ovs doesn't clear skb->tstamp. We encountered a problem with linux version 5.4.56 and ovs version 2.14.1, and packets failed to dequeue from qdisc when fq qdisc was attached to ovs port.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
