fix dpdk and sriov tests by pointing them to the new machine
sriov: polish tests for new machine (i40e based)
Use port and controller names to have cleaner syntax.
dpdk: change device here as well
Use the same sriov-device as before in sriov tests. We need to make pci id dynamic as well. Stay tuned. Let's enable 1G hugepages properly in kernel_post params. Add some checks if hugepages are not set and openvswitch is failing when dpdk cannot be initialized. Do not run tests at all.
