But I look in to the spec of 5719 from Broadcom, it seems that RSS just enable with MSI-X, so I'm not sure if multiple MSI can use RSS. And if multiple MSI can't use RSS, how other usage of the interrupts allocated from the system? Can they be used to improve the performance of the network? Thanks Mike
