Linux kernel source tree

Broadcom PHYs featuring the BroadR-Reach two-wire link mode are usually capable to operate in simplified MII mode, without TXER, RXER, CRS and COL signals as defined for the MII. The absence of COL signal makes half-duplex link modes impossible, however, the BroadR-Reach modes are all full-duplex only. Depending on the IC encapsulation, there exist MII-Lite-only PHYs such as bcm54811 in MLP. The PHY itself is hardware-strapped to select among multiple RGMII and MII-Lite modes, but the MII-Lite mode must be also activated by software. Add MII-Lite activation for bcm5481x 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 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.
