Subject: calibrate: Fix network interface naming
Upstream: merged
Git-commit: 75a44901b54ba853497d63c01bef77b251436e0a

The init scripts may rename the network interface unless it is
given an explicit name by MAC address. If that happens, network
initialization fails, because the "eth0" interface is missing.
