From: Alexander Duyck <alexander.h.duyck@xxxxxxxxx> This change makes it so that both igb and ixgbe can trigger a full pcie function reset if the reset_devices kernel parameter is defined. The main reason for adding this is that kdump can cause serious issues when the kdump kernel resets the IOMMU while DMA transactions are still occurring.
