RDMA/ocrdma: Query and initalize the PFC SL
This patch implements routine to query the PFC priority from the adapter port. Following are the changes implemented: * A new FW command is implemented to query the operational/admin DCBX configuration from the FW and obtain active priority(service level). * Adds support for the async event reported by FW when the PFC priority changes. Service level is re-initialized during modify_qp or create_ah, based on this event. * Maintain SL value in ocrdma_dev structure and refer that as and when needed.
