The setup and configuration of the PMD is not performance sensitive,

read/writes during PMD setup and configuration could be corrupted

sensitive, the developer can choose to add their own layer to provide
thread-safe setup and configuration. It is expected that, in most
applications, the initial configuration of the network ports would be
done by a single thread at startup.

In the case of exception on the event queue, the event queue and
corresponding Rx/Tx queue should be restarted in the Rx/Tx queue
polling context. These operations require access to the device
control which should be serialized. The device level lock will do
the job.
