In WQE (Work Queue Entry), the two types of data segments memories are pointers and inline data, where inline data is passed directly as part of the WQE. For software steering, the maximal inline size should be less than 2*MLX5_SEND_WQE_BB, i.e., the potential data must fit with the required inline WQE headers. Two consecutive blocks (MLX5_SEND_WQE_BB) are not guaranteed to reside on the same memory page. Hence, writes to MLX5_SEND_WQE_BB should be done separately, i.e., each MLX5_SEND_WQE_BB should be obtained using the mlx5_wq_cyc_get_wqe macro.

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.
