Extend the iavf driver to support Receive Side Scaling (RSS) configuration for GTP (GPRS Tunneling Protocol) flows using ethtool. The implementation introduces new RSS flow segment headers and hash field definitions for various GTP encapsulations, including: - GTPC - GTPU (IP, Extension Header, Uplink, Downlink) - TEID-based hashing The ethtool interface is updated to parse and apply these new flow types and hash fields, enabling fine-grained traffic distribution for GTP-based mobile workloads. This enhancement improves performance and scalability for virtualized network functions (VNFs) and user plane functions (UPFs) in 5G and LTE deployments.

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 reStructuredText 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.
