barebox already has a few pytest integration tests but none of them are
networking related. This type of test requires a network connection to
the barebox device, without the "network" feature the test is marked
xfail. DHCP is assumed. For the case of qemu device we also assume DHCP
to set serverip correctly. In any other case, it is set via console to
that IP of the pytest-host that has the route to the barebox devices IP.
The test asserts on a successful ICMP ping from the test device to the
pytest-host as well as on a "No such file or directory" conversation
from the barebox device to the pytest-host
