Selvin Xavier c119d7738c RDMA/bnxt_re: Fix Send Work Entry state check while polling completions
commit c5275723580922e5f3264f96751337661a153c7d upstream.

Some adapters need a fence Work Entry to handle retransmission.  Currently
the driver checks for this condition, only if the Send queue entry is
signalled. Implement the condition check, irrespective of the signalled
state of the Work queue entries

Failure to add the fence can result in access to memory that is already
marked as completed, triggering data corruption, transmission failure,
IOMMU failures, etc.

Fixes: 9152e0b722 ("RDMA/bnxt_re: HW workarounds for handling specific conditions")

README

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.
