Hi Chris,

The linux-lts-utopic test kernel did not have that commit applied since
it is being addressed in bug 1519897.

It sounds like these two bugs should be tied togeter.  What do you
think?  I can rebuild the test kernel with all the commits for this bug
and with commit 8599846d7.

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.
