[SRU][linux-lts-vivid][PATCH 0/2][V2] Fixes for lp1556264

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1556264

== linux-lts-vivid SRU Justification ==
The requested SAUCE patch has been submitted upstream in response to an
investigation of customer issues with network connections hanging under high load.
This patch requires commit a5cca686c as a prereq for linux-lts-vivid.  That commit is a
clean cherry-pick.  This SAUCE patch will also be requeste in Trust, Wily
and Xenial, but each requires a minor variation of the patch.

Commit a5cca686c is in mainline as of v4.30rc1, so Xenial already has it.  Commit 
a5cca686 was applied to Wily via bug 1519917 when a 4.3 rebase was done.
