I tested to change a device touched (initialized) by DPDK, but not yet on an Openvswitch bridge (no port added).
That hangs stalls as well, so it is not required to add it to openvswitch-dpdk.

Next step was to exclude openvswitch completely, therefor I ran testpmd against those ports.
  /usr/bin/testpmd --pci-blacklist 0000:00:03.0 --socket-mem 2048 -- --interactive --total-num-mbufs=2048

After the test I ran ethtool and boom, hangs again.
Test gets simpler and simpler.
