When the driver experiences a link event (especially link up) there can be multiple events generated. Some of these are link fault and still have a state of DOWN set. The problem happens when the link comes UP during the PF driver handling one of the LINK DOWN events. The status of the link is updated and is now seen as UP, so when the actual LINK UP event comes, the port information has already been updated to be seen as UP, even though none of the UP activities have been completed. After the link information has been updated in the link handler and evaluated for MEDIA PRESENT, if the state of the link has been changed to UP, treat the DOWN event as an UP event since the link is now UP.

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.
