Hi,

I've just noticed that the e1000e model does not work with its recent
Linux kernel driver. This is my test matrix:

Kernel          INTx (IntMode=0)        MSI-X
4.4             OK                      OK
4.14            OK                      no link
master          OK                      no link

In MSI-X mode, there are few interrupts arriving:
[...]
 25:          0          0          0          0  IR-PCI-MSI 32768-edge      
enp0s2-rx-0
 26:          0          0          0          0  IR-PCI-MSI 32769-edge      
enp0s2-tx-0
 27:          0          2          0          0  IR-PCI-MSI 32770-edge      
enp0s2

QEMU versions tested without differences: v2.8, v2.9, master.

Any ideas what could go wrong, and where?

Jan
