Hi  Chris and Josh,

I just wanted to let you know I'm still working on the backports for
this bug and bug 1519897 .  There are 22 other commits that are also
required as prerequisites and most need backporting, which it is taking
longer than expected to get a test kernel.

I should have a test kernel available shortly.

Bug description:
  Microsoft has investigated networking with NUMA nodes and Hyper-V and
  found a number of areas where Linux performance could be corrected to
  be in line with other virtual machine types.

  Please include the following commits and their necessary prerequisites
  (which have been accepted upstream into the 4.2 kernel series) into
  the kernels for 15.10, 15.04, 14.04 (including HWE), and 12.04
  (including HWE):
