The SGMII (internal PHY) can report decode errors via an interrupt. It can also report autonegotiation status changes, but we don't need to track those. The SGMII can recover automatically from most decode errors, so we only reset the interface if we get multiple consecutive errors. It's possible for bogus decode errors to be reported while the link is being brought up. The interrupt is registered when the interface is opened, and it's enabled after the link is up.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
