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