Since aqr_gen2_config_init() and aqr_gen2_fill_interface_modes() refer to the feature set common to the same generation, it means all callers of aqr_gen2_config_init() also support the Global System Configuration registers at addresses 1E.31B -> 1E.31F, and these should be read by the driver to figure out the list of supported interfaces for phylink. This affects the following PHYs supported by this driver: - Gen2: AQR107 - Gen3: AQR111, AQR111B0 - Gen4: AQR114C, AQR813. AQR113C, a Gen4 PHY, has unmodified logic after this change, because currently, the aqr_gen2_fill_interface_modes() call is chained after aqr_gen2_config_init(), and after this patch, it is tail-called from the latter function, leading to the same code flow. At the same time, move aqr_gen2_fill_interface_modes() upwards of its new caller, aqr_gen2_config_init(), to avoid a forward declaration.

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 reStructuredText 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.
