Jacob Keller 7362be9eee i40e: reduce lrxqthresh from 2 to 1
The lrxq thresh value tells hardware to immediately interrupt when there
are fewer than N*64 packets left in the ring.

Counter intuitively, empirical testing has shown that decreasing this
value from 2 to 1, and thus changing from an immediate interrupt at
fewer than 128 descriptors down to 64 descriptors causes a small
increase in the maximum total packets per second we can receive. This
increase occurs even when we're polling with interrupts masked, as the
hardware must still handle interrupts internally even if we've disabled
them in software.

Also reduce the value for any VFs we allocate.

README

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.
