961 * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
962 * c. If the FCoE L2 queue is supported the actual number of L2 queues
963 *    is Y+1
964 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
965 *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
966 *    FP interrupt context for the CNIC).
967 * e. The number of HW context (CID count) is always X or X+1 if FCoE
968 *    L2 queue is supported. the cid for the FCoE L2 queue is always X.
