When a link bounce happens, there is a possibility that responses to requests posted prior to the link bounce could be received. This is problematic as the counter to track reglogin completion after link up can become out of sync with the real state. As there is no reason to process a request made in a prior link up context, eliminate all the disturbance by tagging the request with the event_tag maintained by the SLI Port for the link. The event_tag will change on every link state transition. As long as the tag matches the current event_tag, the response can be processed. If it doesn't match, just discard the response.

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.
