Native hardware and KVM do not expose that.

More than that, I have an LSI 2008 adapter which is also being passed through in the same manner as the NIC, absolutely the same problem there too. Before doing the bisect I considered it a separate issue and planned to work on it later. > Could you please give the patch below a try?

Just for the sake of experiment built a clean 4.7 kernel without the patch, issue still present there as expected.
