ocelot_mm_update_port_status() updates mm->verify_status, but when the verification state of a port changes, an IRQ isn't emitted, but rather, only when the verification state reaches one of the final states (like DISABLED, FAILED, SUCCEEDED) - things that would affect mm->tx_active, which is what the IRQ *is* actually emitted for. That is to say, user space may miss reports of an intermediary MAC Merge verification state (like from INITIAL to VERIFYING), unless there was an IRQ notifying the driver of the change in mm->tx_active as well. This is not a huge deal, but for reliable reporting to user space, let's call ocelot_mm_update_port_status() synchronously from ocelot_port_get_mm(), which makes user space see the current MM status.

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.
