In addition to retrieving the device capabilities, a VF may also need to retrieve the mapping of its ring pairs to crypto and or compression services in order to work properly. Make the VF receive the ring-to-service mappings from the PF by means of a new REQ_RING_SVC_MAP Block Message and add the request and response logic on VF and PF respectively. This change requires to bump the PFVF protocol to version 4.
