Radu Pirea says: ==================== Add MACsec support for TJA11XX C45 PHYs This is the MACsec support for TJA11XX PHYs. The MACsec block encrypts the ethernet frames on the fly and has no buffering. This operation will grow the frames by 32 bytes. If the frames are sent back to back, the MACsec block will not have enough room to insert the SecTAG and the ICV and the frames will be dropped. To mitigate this, the PHY can parse a specific ethertype with some padding bytes and replace them with the SecTAG and ICV. These padding bytes might be dummy or might contain information about TX SC that must be used to encrypt the frame. ==================== 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.
