Add support for the per-port interrupt controller that deals with both INTx signalling and management interrupts. This allows the Link-up/Link-down interrupts to be wired, allowing the bring-up to be synchronised (and provide debug information). The framework can further be used to handle the rest of the per port events if and when necessary. Likewise, INTx signalling is implemented so that end-points can actually be used.

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.
