The current implementation of create QP 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 advantage of the new mlx5_core API which allocates a fragmented buffer. This makes the QP creation much more resilient to memory fragmentation. Data-path code was adapted to the fact that WQEs can cross buffers. We also use the opportunity to fix some cosmetic legacy coding convention errors which were in the feature scope.

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.
