Persistent network configuration

[Jiri Svoboda]

Network configuration in HelenOS is not preserved across reboots, even if persistent /w is available. Making it persistent is tricky, since we don't have a way to persistently identify IP links.

The current configuration model is too static and does not account for things like Wi-FI or walking around with a laptop and plugging an Ethernet cable into different networks.

Perhaps the configuration model should be changed to introduce a 'network connection' as the persistent entity against which we would anchor the configuration. Then we would detect network connection on a IP link by examining the SSID (for wireless), HW MAC address (for wired), etc.
