Hi Joe,
We've attempted to validate the linux-lts-utopic test kernel provided, however on a Trusty system the VM is not stable in terms of getting the network connectivity, as during performance testing, the system tend to loose the test interface connection.

Can you please confirm if commit  8599846d73 is checked in?

Bug description:
  hv_netvsc: Use the xmit_more skb flag to optimize signaling the host
  Based on the information given to this driver (via the xmit_more skb flag),
  we can defer signaling the host if more packets are on the way. This will help
  make the host more efficient since it can potentially process a larger batch of
  packets. Implement this optimization.
