commit 211987f3ac734000ea1548784b2a4539a974fbc8 upstream.
ds->ops->port_stp_state_set() is, like most DSA methods, optional, and
if absent, the port is supposed to remain in the forwarding state (as
standalone). Such is the case with the mv88e6060 driver, which does not
offload the bridge layer. DSA warns that the STP state can't be changed
to FORWARDING as part of dsa_port_enable_rt(), when in fact it should not.
The error message is also not up to modern standards, so take the
opportunity to make it more descriptive.
Fixes: fd3645413197 ("net: dsa: change scope of STP state setter")

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.
