Setting 10G without autonegotiation is invalid according to phy_ethtool_ksettings_set(). Thus, we need to set it during autonegotiation. If 1G autonegotiation can't complete for quite a time, but there is signal in line, switch line interface type to 10GBase-R, if supported, in hope for link to be established. And vice versa. If 10GBase-R link can't be established for quite a time, and autonegotiation is enabled, and there is signal in line, switch line interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if supported.

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.
