I use the 3.8-rc2 to test it again, I saw this tag has the multi-tap support.
I just can't start the QEMU use -netdev tap,id=hostnet0,queues=2,fd=%d,fd=%d -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:ce:7b:29,bus=pci.0,addr=0x3
I pre-opened two tap fds, did I missing something?
Thanks,
