[ Upstream commit f01765a2361323e78e3d91b1cb1d5527a83c5cf7 ]
The bnxt_re SEND path checks wr->send_flags to enable features such as
IP checksum offload. However, send_flags is a bitmask and may contain
multiple flags (e.g. IB_SEND_SIGNALED | IB_SEND_IP_CSUM), while the
existing code uses a switch() statement that only matches when
send_flags is exactly IB_SEND_IP_CSUM.
As a result, checksum offload is not enabled when additional SEND
flags are present.
Replace the switch() with a bitmask test:
if (wr->send_flags & IB_SEND_IP_CSUM)
This ensures IP checksum offload is enabled correctly when multiple
SEND flags are 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 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.
