Linux kernel source tree

The .serdes_get_lane op used the magic value 0xff to indicate a valid
SERDES lane and 0 signaled that a non-SERDES mode was set on the port.
Unfortunately, "0" is also a valid lane ID, so even when these ports
where configured to e.g. RGMII the driver would set them up as SERDES
ports.
- Replace 0xff with 0 to indicate a valid lane ID. The number is on
the one hand just as arbitrary, but it is at least the first valid one
and therefore less of a surprise.
- Follow the other .serdes_get_lane implementations and return -ENODEV
in the case where no SERDES is assigned to the port.

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.
