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.
