817 * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
818 * control by the number of fast-path status blocks supported by the
819 * device (HW/FW). Each fast-path status block (FP-SB) aka non-default
820 * status block represents an independent interrupts context that can
821 * serve a regular L2 networking queue. However special L2 queues such
822 * as the FCoE queue do not require a FP-SB and other components like
823 * the CNIC may consume FP-SB reducing the number of possible L2 queues
824 *
825 * If the maximum number of FP-SB available is X then:
826 * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
827 *    regular L2 queues is Y=X-1
828 * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
829 * c. If the FCoE L2 queue is supported the actual number of L2 queues
830 *    is Y+1
831 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
832 *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
833 *    FP interrupt context for the CNIC).
834 * e. The number of HW context (CID count) is always X or X+1 if FCoE
835 *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
836 *
837 * So this is quite simple for now as no ULPs are supported yet. :-)
