When allocating a QP we allocate an RQ and an SQ, the RQ is stored first in memory and followed by the SQ. This allocation is not physically continiuos - it may span across different physical pages. SW Steering code always writes in pairs: 1BB write + 1BB read, or 2 continuous BBs of GTA WQE. This lead to an issue where RQ allocation was 4x16 which is equal to 1 WQE BB, causing 1 BB offset in the page and splitting the GTA WQE between different physical pages. The solution was to create the RQ with a even number of BBs and to have the RQ aligned to a page.

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.
