net/sfc: add init on attach

The setup and configuration of the PMD is not performance sensitive,
but is not thread safe either. It is possible that the multiple
read/writes during PMD setup and configuration could be corrupted
in a multi-thread environment.  Since this is not performance
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.

virtio_dev_info_get(). But if an application tries to start the PMD with
Rx offloads enabled (rxmode.hw_ip_checksum = 1), the initialization of

examples/performance-thread: add packet type parsing

Last changes in Niantic and Fortville NIC drivers causes that
vector Rx path is chosen by default in l3fwd-thread application.
This path doesn't support propagation of hw packet type recognition
to the packet_type field in mbuf, and packets cannot be classified
properly.

The approach to solve this problem is similar to the commit:
71a7e2424e07 ("examples/l3fwd: fix using packet type blindly").

To use sw packet analyzer, new command line option "--parse-ptype" is
introduced.
