Normal RDMA WRITE request never returns IB_WC_RNR_RETRY_EXC_ERR to ULPs
because it does not need post receive buffer on the responder side.
Consequently, as an enhancement to normal RDMA WRITE request inside the
hfi1 driver, TID RDMA WRITE request should not return such an error status
to ULPs, although it does receive RNR NAKs from the responder when TID
resources are not available. This behavior is violated when
qp->s_rnr_retry_cnt is set in current hfi1 implementation.
This patch enforces these semantics by avoiding any reaction to the updates
of the RNR QP attributes.

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.
