788  * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
789  * control by the number of fast-path status blocks supported by the
790  * device (HW/FW). Each fast-path status block (FP-SB) aka non-default
791  * status block represents an independent interrupts context that can
792  * serve a regular L2 networking queue. However special L2 queues such
793  * as the FCoE queue do not require a FP-SB and other components like
794  * the CNIC may consume FP-SB reducing the number of possible L2 queues
795  *
796  * If the maximum number of FP-SB available is X then:
797  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
798  *    regular L2 queues is Y=X-1
799  * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
800  * c. If the FCoE L2 queue is supported the actual number of L2 queues
801  *    is Y+1
802  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
803  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
804  *    FP interrupt context for the CNIC).
805  * e. The number of HW context (CID count) is always X or X+1 if FCoE
806  *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
807  *
808  * So this is quite simple for now as no ULPs are supported yet. :-)
