This patch adds support for driver level TSO in the enetc driver using the TSO API. There is not much to say about this specific implementation. We are using the usual tso_build_hdr(), tso_build_data() to create each data segment, we create an array of S/G FDs where the first S/G entry is referencing the header data and the remaining ones the data portion. For the S/G Table buffer we use the same cache of buffers used on the other non-GSO cases - dpaa2_eth_sgt_get() and dpaa2_eth_sgt_recycle(). We cannot keep a DMA coherent buffer for all the TSO headers because the DPAA2 architecture does not work in a ring based fashion so we just allocate a buffer each time. Even with these limitations we get the following improvement in TCP termination on the LX2160A SoC, on a single A72 core running at 2.2GHz. before: 6.38Gbit/s after: 8.48Gbit/s Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S.

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.
