Add layer 4 RSS hashing on UDP traffic to allow for the utilization of multiple queues for multiple connections on the same IP address. Previously, since the introduction of the driver, RSS hashing was only performed on the source and destination IP addresses of UDP packets thereby limiting UDP traffic to a single queue for multiple connections on the same IP address. The transport layer is now included in RSS hashing for UDP traffic, which was not previously the case. The reason behind the previous limitation is unclear - either a historic limitation of the NFP device, or an oversight.

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.
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.
