                          I have a buildroot embedded Linux where I change the ethernet port settings (i.e. disabled, static or DHCP) from a C++ program. When switching to DHCP, it would be nice to determine when (i.e. timestamp) the device actually gets the DHCP lease.  
How can I determine that?

Polling the current IP address and waiting for a chanage is not an option.
