system-test matrix first runs unit tests and then system tests.
And if unit tests fail, system tests are not run.
This patch now runs only system tests for system-test matrix.
A new entry is added in the test matrix - 'gcc compiler with
unit tests'.

This patch adds support for virtual ports with VIP IPv6 by adding

Problem Statement:
OVS flushes and subsequently repopulates its route
cache whenever it receives a netlink notification
about kernel interface change. At the same time the
port addition triggers a revalidation of all
