Right now, the following would happen for a switch driver that does not
implement .port_fdb_add or .port_fdb_del.
dsa_slave_switchdev_event returns NOTIFY_OK and schedules:
-> dsa_slave_switchdev_event_work
-> dsa_port_fdb_add
-> dsa_port_notify(DSA_NOTIFIER_FDB_ADD)
-> dsa_switch_fdb_add
-> if (!ds->ops->port_fdb_add) return -EOPNOTSUPP;
-> an error is printed with dev_dbg, and
dsa_fdb_offload_notify(switchdev_work) is not called.
We can avoid scheduling the worker for nothing and say NOTIFY_DONE.
Because we don't call dsa_fdb_offload_notify, the static FDB entry will
remain just in the software bridge.

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.
