The following change is meant to update the adaptive ITR algorithm to better support the needs of the network. Specifically with this change what I have done is make it so that our ITR algorithm will try to prevent either starving a socket buffer for memory in the case of Tx, or overrunning an Rx socket buffer on receive. In addition a side effect of the calculations used is that we should function better with new features such as XDP which can handle small packets at high rates without needing to lock us into NAPI polling mode.

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.
