By default gro.sh will use the veth backend, and will try to use exiting H/W in loopback mode if a specific device name is provided with the '-i' command line option. No functional change is intended for the loopback-based tests, just move all the relevant initialization/cleanup code into the related script. Introduces a new initialization helper script for the veth backend, and plugs the correct helper script according to the provided command line. Additionally, enable veth-based tests by default. v1 -> v2: - drop unused code in setup_veth_ns() - Willem Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
