Currently there is no validation on the spectral/CFR report over the db ring buffers from the hardware. Improper/incomplete DMA by the target can result in invalid data received by host. Due to this we may populate incorrect data to user space. This buffer validation support fix this issues by filling some magic value in the buffer during buffer replenish and check for the magic value in the buffer received by the target. If host detect magic value in the received buffer it will drop the buffer.

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.
