Whenever users provided affinity for an EQ creation request, map the EQ to a matching IRQ. Matching IRQ=IRQ with the same affinity and type (completion/control) of the EQ created. This mapping is being done in agressive dedicated IRQ allocation scheme, which described bellow. First, we check whether there is a matching IRQ that his min threshold is not exhausted. - min_eqs_threshold = 3 for control EQ. - min_eqs_threshold = 1 for completion EQ. In case no matching IRQ was found, try to request a new IRQ. In case we can't request a new IRQ, reuse least-used matching IRQ.
