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.

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.
