[ Upstream commite239c6d686] In striding RQ mode, the buffers of an RX WQE are first prepared and posted to the HW using a UMR WQEs via the ICOSQ. We maintain the state of these in-progress WQEs in the RQ SW struct. In the flow of ICOSQ recovery, the corresponding RQ is not in error state, hence: - The buffers of the in-progress WQEs must be released and the RQ metadata should reflect it. - Existing RX WQEs in the RQ should not be affected. For this, wrap the dealloc of the in-progress WQEs in a function, and use it in the ICOSQ recovery flow instead of mlx5e_free_rx_descs().

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.
