requests. Increasing this will allow U-Boot to accept offers
from a BOOTP client in networks with unusually high latency.
+- BOOTP Random transaction ID:

+ The standard algorithm to generate a DHCP/BOOTP transaction ID

- DHCP Advanced Options:
You can fine tune the DHCP functionality by defining
CONFIG_BOOTP_* symbols:
This enables the RSA algorithm used for FIT image verification
in U-Boot. See doc/uImage.FIT/signature.txt for more information.
