Yes, there's a known issue with UDP, where we don't report congestion and the queues start dropping packets. There's a patch for tun queued for the next merge window; you'll need a 2.6.31 host for that IIRC (Herbert?)

It should be in 2.6.30 in fact.  However, this is for outbound

of the guest sending faster than the wire.

Is there a corresponding qemu change? Or is this a already handled by the existing code?
