Linux kernel source tree
1f92ead7e1
There is an interdependence between the current link_an_mode and pcs_neg_mode that some drivers rely upon to know whether inband or PHY mode will be used. In order to support detection of PCS and PHY inband capabilities resulting in automatic selection of inband or PHY mode, we need to cater for this, and support changing the MAC link_an_mode. However, we end up with an inter-dependency between the current link_an_mode and pcs_neg_mode. To solve this, split the current link_an_mode into the requested link_an_mode and active link_an_mode. The requested link_an_mode will always be passed to phylink_pcs_neg_mode(), and the active link_an_mode will be used for everything else, and only updated during phylink_major_config(). This will ensure that phylink_pcs_neg_mode()'s link_an_mode will not depend on the active link_an_mode that will, in a future patch, depend on pcs_neg_mode.

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.
