884 * c. If the FCoE L2 queue is supported the actual number of L2 queues
886 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
887 * slow-path interrupts) or Y+2 if CNIC is supported (one additional
888 * FP interrupt context for the CNIC).
889 * e. The number of HW context (CID count) is always X or X+1 if FCoE
890 * L2 queue is supported. the cid for the FCoE L2 queue is always X.
