The current implementation of create SRQ requires contiguous memory, such a requirement is problematic once the memory is fragmented or the system is low in memory, it causes failures in dma_zalloc_coherent(). This patch takes the advantage of the new mlx5_core API which allocates a fragmented buffer, and makes the SRQ creation much more resilient to memory fragmentation. Data-path code was adapted to the fact that WQEs can cross buffers.

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.
