Support QP with out-of-order (OOO) capabilities enabled. This allows WRs on the receiver side of the QP to be consumed OOO, permitting the sender side to transmit messages without guaranteeing arrival order on the receiver side. When enabled, the completion ordering of WRs remains in-order, regardless of the Receive WRs consumption order. RDMA Read and RDMA Atomic operations on the responder side continue to be executed in-order, while the ordering of data placement for RDMA Write and Send operations is not guaranteed. Atomic operations larger than 8 bytes are currently not supported. Therefore, when this feature is enabled, the created QP restricts its atomic support to 8 bytes at most. In addition, when querying the device, a new flag is returned in response to indicate that the Kernel supports OOO QP.

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.
