[Bug 1454892] Re: [Hyper-V] hv_netvsc: Use the xmit_more skb flag to optimize signaling the host

 

I think that is just showing temporary changes where in linux-lts-utopic
was marked as affecting Precise, Utopic, Vivid and Wily.  However, there
is no lts utopic kernel for those releases, there is only one for
trusty, and that was was marked as "Fix Commited".  So the fix is still
coming as expected.

** Changed in: linux-lts-utopic (Ubuntu)
       Status: New => Fix Committed

** Changed in: linux-lts-utopic (Ubuntu)
   Importance: Undecided => High

** Changed in: linux-lts-utopic (Ubuntu Trusty)
   Importance: Undecided => High

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.
