When device is behind the IOMMU, VirtioNetDxe is required to use the device address in bus master operations. RxBuf is allocated using AllocatePool() which returns the system physical address. The patch uses VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages() to allocate the RxBuf and map with VirtioMapAllBytesInSharedBuffer() so that we can obtain the device address for RxBuf.
