Pull Request: [Vivid][SRU]Pull Request: Hyper-V network optimization for Vivid requested in lp1454892

[Joseph Salisbury]

Hmm, this happened once before.  git send-mail left off the first few
lined of my message.  It should begin:

"Bug 1454892 is a request for a network optimization (commit 82fa3c776
in mainline).
This commit is Hyper-V specific and is requested in all stable Ubuntu
releases. 
However, there are several prerequisites required for this commit.  This
pull request is for
the single network optimization commit and all it's prerequisites."
