> you probably want to be using MSI-X for a 10G NIC instead of INTx anyway. Why do you say that? Is MSI-X faster than INTx in terms of interrupt latency? When should I use MSI-X, instead of fast filters interrupts (fast interrupt?), instead of ithread interrupts? Thanks in advace. Regards, Matteo -- http://www.matteolandi.net/
