The dhcp-all-interfaces element does not work with the predictable names scheme, fallback to the persistent names scheme as workaround. Bug: 1960301 Change-Id: I117964a60615a5b7e9984f52f02cd018d1a48ed0

# shutting down the port between retries which is critical for recovery

# from LACP port blocking situations. As such, we'll force it to dhclient.
