Having the interrupts firing while we are polling causes extra overhead and isn't needed for most systems out there. If an interrupt is lost us experiencing a 2s latency spike before recovering is still not acceptable and masks the issue. We are better off just identifying systems that lose interrupts and instead enable workarounds for those systems. To that end I am dropping the code that was strobing the interrupts as there is a narrow window where having them enabled can actually cause race issues anyway where a few stray packets might get misses if the interrupt is re-enabled and fires before we call napi_complete.

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.
