Add support for adaptive TX moderation. This greatly reduces TX interrupt rate and increases bandwidth, mostly for TCP bandwidth over ARM architecture (below). There is a slight single stream TCP with very large message sizes degradation (x86). In this case if there's any moderation on transmitted packets the bandwidth would reduce due to hitting TCP output limit. Since this is a synthetic case, this is still worth doing. Performance improvement (ConnectX-4Lx 40GbE, ARM) TCP 64B bandwidth with 1-50 streams increased 6-35%. TCP 64B bandwidth with 100-500 streams increased 20-70%. Performance improvement (ConnectX-5 100GbE, x86) Bandwidth: increased up to 40% (1024B with 10s of streams). Interrupt rate: reduced up to 50% (1024B with 1000s of streams). Performance degradation (ConnectX-5 100GbE, x86) Bandwidth: up to 10% decrease single stream TCP (1MB message size from 51Gb/s to 47Gb/s).

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.
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.
