I have had the same problem, as shown here:

According to your pciconf output, your card either doesn't support
MSI-X, or you have MSI-X disabled.
Check the hw.pci.enable_msix sysctl and make sure that it is set to 1.
Also check to make sure there aren't any BIOS settings blocking MSI-X.
Apparently the older Intel gigabit cards don't support MSI-X, and as
such get starved.
Upgraded to a new bios, but that does not help either.
Now the trick question will be:
IF I get a new servertype PCI-E ethernet card, would that get me
an MSI-X ethernet device.
