Oh. ok. It also looks like even with the reverted patch, mlx4 VF does not
work in a guest:
So where is the breakage point for you? does 4.4 works? if not, what?
Ah, my bad. It is unrelated to the kernel version.
I tried passing a PF to a guest while its VFs are already passed to another
guest and see how exactly it blows up (AER/EEH were thrown but the host
recovered => good) but this left the device in a weird state when I could
not use VF in a guest anymore but it seemed to keep working on the host.
It seems like the actual adapter does not reset completely when the machine
is rebooted, I had unplug/replug power cables to fix this.
