820  * as the FCoE queue do not require a FP-SB and other components like
821  * the CNIC may consume FP-SB reducing the number of possible L2 queues
822  *
823  * If the maximum number of FP-SB available is X then:
824  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
825  *    regular L2 queues is Y=X-1
826  * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
827  * c. If the FCoE L2 queue is supported the actual number of L2 queues
828  *    is Y+1
829  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
830  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
831  *    FP interrupt context for the CNIC).
832  * e. The number of HW context (CID count) is always X or X+1 if FCoE
833  *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
834  *
