Subject: Re: [RFC/PATCH 4/16] Abstract MSI suspend

OK, I should look before I post. But anyway a quick grep shows that
the forcedeth driver does enable MSI-X for at least some devices. And
a quick look at the nv_suspend() function makes me think that suspend
probably won't work if MSI-X is used, since it doesn't save the MSI-X
state anywhere that I can see (unless the device is magic enough to
keep the MSI-X table in some sort of persistent storage, which I
highly doubt).
