I'd disagree: as soon as the IOMMU is reconfigured/reused Network Rx
could become a problem: it could point to new io areas of the kexec'ed
kernel.

Btw, what's the preferred approach to clear the pci master bit:
forcedeth writes to freed buffers after ifdown right now. I'll add a
reset into the _close function, but disabling the master bit is probably
better.
