519 * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
520 * control by the number of fast-path status blocks supported by the
521 * device (HW/FW). Each fast-path status block (FP-SB) aka non-default
522 * status block represents an independent interrupts context that can
523 * serve a regular L2 networking queue. However special L2 queues such
524 * as the FCoE queue do not require a FP-SB and other components like
525 * the CNIC may consume FP-SB reducing the number of possible L2 queues
527 * If the maximum number of FP-SB available is X then:
528 * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
529 * regular L2 queues is Y=X-1
530 * b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
531 * c. If the FCoE L2 queue is supported the actual number of L2 queues
533 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
534 * slow-path interrupts) or Y+2 if CNIC is supported (one additional
535 * FP interrupt context for the CNIC).
536 * e. The number of HW context (CID count) is always X or X+1 if FCoE
537 * L2 queue is supported. the cid for the FCoE L2 queue is always X.
539 * So this is quite simple for now as no ULPs are supported yet. :-)
