* The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
* control by the number of fast-path status blocks supported by the
* device (HW/FW). Each fast-path status block (FP-SB) aka non-default
* status block represents an independent interrupts context that can
* serve a regular L2 networking queue. However special L2 queues such
* as the FCoE queue do not require a FP-SB and other components like
* the CNIC may consume FP-SB reducing the number of possible L2 queues
*
* If the maximum number of FP-SB available is X then:
* a. If CNIC is supported it consumes 1 FP-SB thus the max number of
* regular L2 queues is Y=X-1
* b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
* c. If the FCoE L2 queue is supported the actual number of L2 queues
* is Y+1
* d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
* slow-path interrupts) or Y+2 if CNIC is supported (one additional
* FP interrupt context for the CNIC).
* e. The number of HW context (CID count) is always X or X+1 if FCoE
* L2 queue is supported. the cid for the FCoE L2 queue is always X.
