The first fact that needs to be stated is that the per-MAC settings in SJA1105 called EGRESS and INGRESS do *not* disable egress and ingress on the MAC. They only prevent non-link-local traffic from being sent/received on this port. So instead of having .phylink_mac_config essentially mess with the STP state and force it to DISABLED/BLOCKING (which also brings useless complications in sja1105_static_config_reload), simply add the .phylink_mac_link_down and .phylink_mac_link_up callbacks which inhibit TX at the MAC level, while leaving RX essentially enabled. Also stop from trying to put the link down in .phylink_mac_config, which is incorrect.

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.
