                CONFIG_BOOTP_SERVERIP - TFTP server will be the serverip
                environment variable, not the BOOTP server.
 
+               CONFIG_BOOTP_MAY_FAIL - If the DHCP server is not found
+               after the configured retry count, the call will fail
+               instead of starting over.  This can be used to fail over
+               to Link-local IP address configuration if the DHCP server
+               is not available.
+
                CONFIG_BOOTP_DNS2 - If a DHCP client requests the DNS
                serverip from a DHCP server, it is possible that more
                than one DNS serverip is offered to the client.
