The xpcs_switch_interface_mode function was introduced to handle interface switching. According to the XPCS datasheet, a soft reset is required to initiate Clause 37 auto-negotiation when the XPCS switches interface modes. When the interface mode switches from 2500BASE-X to SGMII, re-initiating Clause 37 auto-negotiation is required for the SGMII interface mode to function properly.

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.
