Since the slave unicast address is synced to hardware and to the DSA
master during dsa_slave_open(), this means that a call to
dsa_slave_set_mac_address() while the slave interface is down will
result to a call to dsa_port_standalone_host_fdb_del() and to
dev_uc_del() for the MAC address while there was no previous
dsa_port_standalone_host_fdb_add() or dev_uc_add().
This is a partial revert of the blamed commit below, which was too
aggressive.

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.
