iSCSI hook and IOMMU
I've observed issues when using iSCSI sanhook in conjunction with the IOMMU. When the loaded kernel enables the IOMMU, the traffic caused by the iSCSI hook eventually causes DMA faults, because the NIC uses DMA regions that are not registered anywhere.

Since iPXE acts like a kind of firmware in this case, shouldn't it register the NIC and corresponding memory regions in the RMRRs?
