777  * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
778  * control by the number of fast-path status blocks supported by the

780  * status block represents an independent interrupts context that can
781  * serve a regular L2 networking queue. However special L2 queues such
782  * as the FCoE queue do not require a FP-SB and other components like
783  * the CNIC may consume FP-SB reducing the number of possible L2 queues
784  *
785  * If the maximum number of FP-SB available is X then:
786  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
787  *    regular L2 queues is Y=X-1
788  * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
789  * c. If the FCoE L2 queue is supported the actual number of L2 queues
790  *    is Y+1
791  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
792  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
793  *    FP interrupt context for the CNIC).
794  * e. The number of HW context (CID count) is always X or X+1 if FCoE
795  *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
796  *
797  * So this is quite simple for now as no ULPs are supported yet. :-)
