Modify xskq_cons_read_desc_batch() in a way that each processed descriptor will be checked if it is an EOP one or not and act accordingly to that. Change the behavior of mentioned function to break the processing when stumbling upon invalid descriptor instead of skipping it. Furthermore, let us give only full packets down to ZC driver. With these two assumptions ZC drivers will not have to take care of an intermediate state of incomplete frames, which will simplify its implementations a lot. Last but not least, stop processing when count of frags would exceed max supported segments on underlying device.

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.
