Do I have to send an email to the maintainer of the ixgbe driver and
ask him to update the comments, or

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.

Hi everybody,
trying to measure the interrupt latency of a 10G Intel network
adapter, I find out that the the used driver (ixgbe) can can be
configured to work with both fast and standard interrupts. From my
understanding of the BUS_SETUP_INTR(9) man page and
sys/kern/kern_intr.c file, it seems th
