I'll nip the usual set of questions in the bud: Not all Ethernet hardware indicates that the link beat status has changed. Some Ethernet hardware doesn't even provide the link beat status info So there is no generic way to do this. Right now the best way to do this is to use a program like 'mii-diag' in polling mode to check for link beat. When you detect link beat, start up the DHCP client.
