Bug Description

Recently openvswitch-dpdk testcases failed => https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-xenial/xenial/amd64/o/openvswitch-dpdk/20160217_200054@/log.gz

While in the discussion it did not become clear why/how they ever worked the issue was found being a lack of sse3 in the test environment.
But that is a minumum requirement for the code to work and therefore it was "correct" that the tests failed there.
All tests worked just fine in either physical environments or vm's which were augmented by --qemu-options='-cpu qemu64,+ssse3'.

In a discussion on #ubuntu-devel it was decided that this is way too test specific and the tests should detect that issue and skip the tests.

FYI - this was also blocking the migration of the last DPDK 2.2 upload which in turn is a pre-req to build openvswitch-dpdk in version 2.5 as the other openvswitch components.

Patch completed, tests with and without --qemu-options='-cpu qemu64,+ssse3' confirm that the tests still run in environments where sse3 is available.

With sse3:

OK

Without sse3:

for adt-virt-qemu please consider adding --qemu-options='-cpu qemu64,+ssse3'
