When device is behind the IOMMU, driver is require to pass the device address of caller-supplied transmit buffer for the bus master operations. The patch uses VirtioNetMapTxBuf() to map caller-supplied Tx packet to a device-address and enqueue the device address in VRING for transfer and perform the reverse mapping when transfer is completed so that we can return the caller-supplied buffer.
