udhcpc can't handle ethernet hotplug #154

Hi,

I set eth1 in dhcp mode. When I plug ethernet cable to eth1, udhcpc will add default gw in route table, but when I unplug it, udhcpc will not delete the default gw.

I see connman is installed in IOT2040. Could connman handle it?

Thanks.

I suspect you can solve that with both, with udhcp via a ifdown script e.g.
