2a5a433ba5 net/sfc: enable TSO by default
Remove RTE_LIBRTE_SFC_EFX_TSO config option since it is not
required any more:
 - unreasonable limit on number of Tx queues when TSO is not
   actually required should be solved using per-device parameter
 - performance difference with and without TSO compiled in is small

ba641f2076 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.
