This commit adds the support for two related features: - Support for TX interrupts, with one interrupt for each CPU - Support for different RX queue distribution modes MVPP2_QDIST_SINGLE_MODE where a single interrupt, shared by all CPUs, receives the RX events, and MVPP2_QDIST_MULTI_MODE, where the per-CPU interrupts used for TX events are also used for RX events. Since additional interrupts are needed, an update to the Device Tree binding is needed. However, backward compatibility is preserved with the old Device Tree binding, by gracefully degrading to the original behavior, with only one RX interrupt, and TX completion being handled by an hrtimer.

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.
