Vineeth Karumanchi d739ce4beb net: macb: Add capability-based QBV detection and Versal support
The 'exclude_qbv' bit in the designcfg_debug1 register varies across
MACB/GEM IP revisions, making direct probing unreliable for detecting
QBV support. This patch introduces a capability-based approach for
consistent QBV feature identification across the IP family.

Platform support updates:
- Establish foundation for QBV detection in TAPRIO implementation
- Enable MACB_CAPS_QBV for Xilinx Versal platform configuration
- Fix capability line wrapping, ensuring code stays within 80 columns

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.
