This patch looks better than previous one for guest to host TCP_STREAM performance. The transmission queue full still exists, but TCP_STREAM results is 43xxMb/s (userspace is about 3500Mb/s). When I increase the transmission queue size to 1K, The performance burst up to 53xxMb/s. But some runs I still hit several transmission queue full in 60 secs run even with 1K queue size.
