The function that releases SHAMPO header pages (mlx5e_shampo_dealloc_hd) has some complicated logic that comes from the fact that it is called twice during teardown: 1) To release the posted header pages that didn't get any completions. 2) To release all remaining header pages. This flow is not necessary: all header pages can be released from the driver side in one go. Furthermore, the above flow is buggy. Taking the 8 headers per page example: 1) Release fragments 5-7. Page will be released. 2) Release remaining fragments 0-4. The bits in the header will indicate that the page needs releasing. But this is incorrect: page was released in step 1. This patch releases all header pages in one go. This simplifies the header page cleanup function. For consistency, the datapath header page release API (mlx5e_free_rx_shampo_hd_entry()) is used.

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.
