Implement single-pair BroadR-Reach modes on bcm5481x PHY by Broadcom. Create set of functions alternative to IEEE 802.3 to handle configuration of these modes on compatible Broadcom PHYs. There is only subset of capabilities supported because of limited collection of hardware available for the development. For BroadR-Reach capable PHYs, the LRE (Long Reach Ethernet) alternative register set is handled. Only bcm54811 PHY is verified, for bcm54810, there is some support possible but untested. There is no auto-negotiation of the link parameters (called LDS in the Broadcom terminology, Long-Distance Signaling) for bcm54811. It should be possible to enable LDS for bcm54810.

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.
