[PATCH v4 1/6] virtio-net: Stop doing DMA from the stack

From: "Michael S. Tsirkin" Once virtio starts using the DMA API, we won't be able to safely DMA from the stack. virtio-net does a couple of config DMA requests from small stack buffers -- switch to using dynamically-allocated memory. This should have no effect on any performance-critical code
