http://0pointer.de/lennart/projects/ifplugd/ In openwrt: CONFIG_BUSYBOX_CONFIG_IFPLUGD or DHCP is unaware of any link changes, it will only renegotiate DHCP lease when lease time has elapsed.. so you could set dhcp lease time shorter (if you have control over DHCP server), like every 1 (or 5) minutes... that way (longer) link interrupts are caught more quickly by the DHCP daemon.
