[ Upstream commit 396ef64113a8ba01c46315d67a99db8dde3eef51 ] If a flow cannot be offloaded, the code currently repeatedly tries again as quickly as possible, which can significantly increase system load. Fix this by limiting flow timeout update and hardware offload retry to once per second.

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.
