- port_fdb_prepare: bridge layer function invoked when the bridge prepares the
installation of a Forwarding Database entry. If the operation is not
supported, this function should return -EOPNOTSUPP to inform the bridge code
to fallback to a software implementation. No hardware setup must be done in
this function. See port_fdb_add for this and details.
