821  * as the FCoE queue do not require a FP-SB and other components like
822  * the CNIC may consume FP-SB reducing the number of possible L2 queues
823  *
824  * If the maximum number of FP-SB available is X then:
825  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
826  *    regular L2 queues is Y=X-1
827  * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
828  * c. If the FCoE L2 queue is supported the actual number of L2 queues
829  *    is Y+1
830  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
831  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
832  *    FP interrupt context for the CNIC).
833  * e. The number of HW context (CID count) is always X or X+1 if FCoE
834  *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
835  *
