Comment 8 for bug 1737211

I was looking into that and it seems vmxnet3 is totally fine.
But e1000e has build issues.
I think I have seen this kind of issue on rom builds in the past but couldn't get it working reliably. OTOH e1000e is only the emulated card and vmxnet3 probably way more important.
So better to add this than nothing.

FYI: the error boils down to:
