CONFIG_BOOTP_VENDOREX

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

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.
