commit283d736ff7upstream. Tx side sets EOP and RS bits on descriptors to indicate that a particular descriptor is the last one and needs to generate an irq when it was sent. These bits should not be checked on completion path regardless whether it's the Tx or the Rx. DD bit serves this purpose and it indicates that a particular descriptor is either for Rx or was successfully Txed. EOF is also set as loopback test does not xmit fragmented frames. Look at (DD | EOF) bits setting in ice_lbtest_receive_frames() instead of EOP and RS pair.

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.
