With 8d66bdf the port configuration of TP-Link Archer C7 has been
changed to a single-interface configuration.
This had unforseen side effects on upgraded devices. Because WANDEV
is evaluated from the updated network.* file, the port configuration
of the switch is evaluated from the update-safe network.config, which
is now incompatible with the updated interface configuration.
Therefore, a migration script has to be added, which updates the port
configuration in network.config to the new single-interface network
configuration.
