Junxian Huang fa5867c496 RDMA/hns: Fix wrong WQE data when QP wraps around 
[ Upstream commit fe9622011f ]

When QP wraps around, WQE data from the previous use at the same
position still remains as driver does not clear it. The WQE field
layout differs across different opcodes, causing that the fields
that are not explicitly assigned for the current opcode retain
stale values, and are issued to HW by mistake. Such fields are as
follows:

* MSG_START_SGE_IDX field in ATOMIC WQE
* BLOCK_SIZE and ZBVA fields in FRMR WQE
* DirectWQE fields when DirectWQE not used

For ATOMIC WQE, always set the latest sge index in MSG_START_SGE_IDX
as required by HW.

For FRMR WQE and DirectWQE, clear only those unassigned fields
instead of the entire WQE to avoid performance penalty.

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 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.
