I am not certain if SR-IOV is toggled on or off in the motherboard
firmware, but I will look this evening. In the meantime, are you aware of a
way to determine that without entering the firmware? I can tell you that
"Intel Virtualization Tech" and "Intel VT-d" are both disabled, and that
the kernel is using SWIOTLB, not iommu.
I moved the IRQ vector for TxRx0 to core 1, and back to core 0, no change
in the DCA_RXCTRL[000].
