In VSC9959, the PCS is the one who performs rate adaptation (symbol duplication) to the speed negotiated by the PHY. The MAC is unaware of that and must remain configured for gigabit. If it is configured at OCELOT_SPEED_10 or OCELOT_SPEED_100, it'll start transmitting PAUSE frames out of control and never recover, _even if_ we then reconfigure it at OCELOT_SPEED_1000 afterwards. This patch fixes a bug that luckily did not have any functional impact. We were writing 10, 100, 1000 etc into this 2-bit field in DEV_CLOCK_CFG, but the hardware expects values in the range 0, 1, 2, 3. So all speed values were getting truncated to 0, which is OCELOT_SPEED_2500, and which also appears to be fine.

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.
