The cpp bridge service is needed for some debug tools, and should be
optional, so remove the mandatory requirement of service lcore parameter.
Fixes: b18804219537 ("net/nfp: add initial flower firmware support")

Add the flow stats process logic in the ctrl VNIC service.
The flower firmware pass the flow stats to nfp driver through
control message, we store them in the flow_priv structure.

From: Chaoyong He @ 2022-10-18 3:12 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Add the flow validate/create/query/destroy/flush API of nfp PMD.
The flow create API construct a control cmsg and send it to
firmware, then add this flow to the hash table.
The flow query API get flow stats from the flow_priv structure.
Note there exist an rte_spin_lock to prevent the update and query
action occur at the same time.
The flow destroy API construct a control cmsg and send it to
firmware, then adelete this flow from the hash table.
The flow flush API just iterate the flows in hash table and
call the flow destroy API.
