When monitor block in Hardware experiences internal backpressure, a ring entry with the EMPTY_DESC reason is received in the monitor destination ring descriptor. The cookie field for this corresponding entry is invalid. Currently driver attempts to process this cookie resulting in invalid buf_id warning logs flooding the console. To fix this, skip processing the destination descriptor when the EMPTY_DESCRIPTOR bit is set to true in ring descriptor, thereby avoiding the processing of junk cookies.

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.
