If the network device supplies a supported interface bitmap, we can use that during phylink's validation to simplify MAC drivers in two ways by using the supported_interfaces bitmap to: 1. reject unsupported interfaces before calling into the MAC driver. 2. generate the set of all supported link modes across all supported interfaces (used mainly for SFP, but also some 10G PHYs.)

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.
