952 * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
953 * c. If the FCoE L2 queue is supported the actual number of L2 queues
954 *    is Y+1
955 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
956 *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
957 *    FP interrupt context for the CNIC).
958 * e. The number of HW context (CID count) is always X or X+1 if FCoE
959 *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
