For the RX flow this has the effect of using different interrupt vectors when using low level drivers (such as mlx4) that map the "vector" param provided by the ULP on CQ creation to a dedicated IRQ/MSI-X vector. This allows the RX flow processing of IO responses to be distributed across multiple CPUs. QPs (--> iSER sessions) are assigned to CQs in round robin order using the CQ with the minimum number of sessions attached to it.
