The 16-bit Port Policy CTL register from older chips is on 6393x changed to Port Policy MGMT CTL, which can access more data, but indirectly and via 8-bit registers. The original 16-bit value is divided into first two 8-bit register in the Port Policy MGMT CTL. We can therefore use the previous code to compute the mask and shift, and then - if 0 <= shift < 8, we access register 0 in Port Policy MGMT CTL - if 8 <= shift < 16, we access register 1 in Port Policy MGMT CTL There are in fact other possible policy settings for Amethyst which could be added here, but this can be done in the future.

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.
