Antoine Tenart says: ==================== net: macsec: remove the preparation phase when offloading operations It was reported[1] the 2-step phase offloading of MACsec operations did not fit well and device drivers were mostly ignoring the first phase (preparation). In addition the s/w fallback in case h/w rejected an operation, which could have taken advantage of this design, never was implemented and it's probably not a good idea anyway (at least unconditionnally). So let's remove this logic which only makes the code more complex for no advantage, before there are too many drivers providing MACsec offloading. This series removes the first phase (preparation) of the MACsec h/w offloading. The modifications are split per-driver and in a way that makes bissection working with logical steps; but I can squash some patches if needed. This was tested on the MSCC PHY but not on the Altantic nor mlx5e NICs.

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.
