Introduce struct mlx5e_xmit_data_frags to be used for non-linear xmit buffers. Let it include sinfo pointer. Take one bit from the len field to indicate if the descriptor has fragments and can be casted-up into the extended version. Zero-init to make sure has_frags, and potentially future fields, are zero when not explicitly assigned. Another field will be added in a downstream patch to indicate and point to dma addresses of the different frags, for redirect-in requests. This simplifies the mlx5e_xmit_xdp_frame/mlx5e_xmit_xdp_frame_mpwqe functions params. Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
