Hello Michael,

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.

Thanks
Shirley
