e1000 and MSI: Is it working?
I created a new build of 6.5.0 SP1 using pci-bios-v2. My board has an intel 82574L which is capable of MSI and MSI-X.
However, when I run the system it appears it is still using a hardline interrupt. How can I tell if MSI is working?
Should the interrupt line be something higher than 15 when MSI is working or am I looking in the wrong place?
My issue is that I have two 82574L based ports. One gets IRQ5 and the other IRQ11. Well, my USB is getting IRQ10 and
IRQ11. So the NIC with IRQ11 becomes unstable when using the USB while the net traffic is heavy. So I was hoping MSI
would solve my problem by getting the NICs off the legacy lines.
A PCI output is attached.
Any insight would be greatly welcomed.
