Implement "mdd-auto-reset-vf" priv-flag to handle Tx and Rx MDD events for VFs. This flag is also used in other network adapters like ICE. Usage: - "on" - The problematic VF will be automatically reset if a malformed descriptor is detected. - "off" - The problematic VF will be disabled. In cases where a VF sends malformed packets classified as malicious, it can cause the Tx queue to freeze, rendering it unusable for several minutes. When an MDD event occurs, this new implementation allows for a graceful VF reset to quickly restore operational state. Currently, VF queues are disabled if an MDD event occurs. This patch adds the ability to reset the VF if a Tx or Rx MDD event occurs. It also includes MDD event logging throttling to avoid dmesg pollution and unifies the format of Tx and Rx MDD messages. Note: Standard message rate limiting functions like dev_info_ratelimited() do not meet our requirements. Custom rate limiting is implemented, please see the code for details.

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.
