There are currently only two methods (xpcs_find_compat() and xpcs_get_interfaces()) defined in the driver which loop over the available interfaces. All of them rely on the xpcs_compat::num_interfaces field value to get the total number of supported interfaces. Thus the interface arrays are supposed to be filled with actual interface IDs and there is no need in the dummy terminating ID placed at the end of the arrays. Based on the above drop the PHY_INTERFACE_MODE_MAX entry from the xpcs_2500basex_interfaces array and the PHY_INTERFACE_MODE_MAX-based conditional statement from the xpcs_get_interfaces() method as redundant.

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.
