buf_info structures in RX & TX queues are private driver data that do not need to be visible to the device. Although there is physical address and length in the queue descriptor that points to these structures, their layout is not standardized, and device never looks at them. So lets allocate these structures in non-DMA-able memory, and fill physical address as all-ones and length as zero in the queue descriptor. That should alleviate worries brought by Martin Radev in https://lists.osuosl.org/pipermail/intel-wired-lan/Week-of-Mon-20210104/022829.html that malicious vmxnet3 device could subvert SVM/TDX guarantees.
