790  * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is

793  * status block represents an independent interrupts context that can
794  * serve a regular L2 networking queue. However special L2 queues such
795  * as the FCoE queue do not require a FP-SB and other components like
796  * the CNIC may consume FP-SB reducing the number of possible L2 queues
797  *
798  * If the maximum number of FP-SB available is X then:
799  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
800  *    regular L2 queues is Y=X-1
801  * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
802  * c. If the FCoE L2 queue is supported the actual number of L2 queues
803  *    is Y+1
804  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
805  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
806  *    FP interrupt context for the CNIC).
807  * e. The number of HW context (CID count) is always X or X+1 if FCoE
808  *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
809  *
810  * So this is quite simple for now as no ULPs are supported yet. :-)
