I see what you mean now. qemu itself has no direct support for persistent tuntap
devices.

However, I imagine that one could modify tundev.c or tapdev.c to open a 
persistent
tuntap device (by name) and then pass the fd to qemu via -tun-fd. It would be
better if qemu had direct support for them of course.
