[SRU][Bionic][PATCH 0/2] Fixes for LP:1776927

[Joseph Salisbury]

== SRU Justification ==
Running up two containers using ipvlan with IPv6 autoconf active triggers 
an assertion failure in the kernel (cloud image running on Brightbox).
This is a regression caused by commit e9997c2938b2. 

This regression is fixed by commit 8230819494b3 but also requires commit 94333fac44d1 
as a prereq.

== Fixes ==
94333fac44d1 ("ipvlan: drop ipv6 dependency")
8230819494b3 ("ipvlan: use per device spinlock to protect addrs list updates")

== Regression Potential ==
Low.  Fixes a current regression.  The fix was also sent to stable, so
it has had additional upstream review.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
