Limit the maximal queue size for RDMA controllers. Today, the target reports a limit of 1024 and this limit isn't valid for some of the RDMA based controllers. For now, limit RDMA transport to 128 entries (the max queue depth configured for Linux NVMe/RDMA host). Future general solution should use RDMA/core API to calculate this size according to device capabilities and number of WRs needed per NVMe IO request.

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.
