Howdy! Observation: virtio-net.c hard-codes the vring size to 256 buffers.
Could this reasonably be made configurable, or would that be likely to cause a problem? In Snabb Switch we are creating a 1:1 mapping between Virtio-net descriptors and VMDq hardware receive descriptors. The VMDq queues support 32768 buffers and I'd like to match this on the QEMU/Virtio-net side -- or at least come close. Cheers! -Luke
