Looking at the source code is the easiest way to answer this question.
Currently there is no clean way to stop the DHCP client. But it looks
very easy for you to add this functionality. You need to extend
dhcp_mgt_entry() in dhcp_support.c to allow you to break the thread
out and exit. Once the thread is dead you can then call init_net with
a bootp record you create using your static IP addresses.
