Since RCMP+ is a UDP based protocol, and UDP has support for checksumming, I can't think of a problematic situation for the layer 7 checksum computation. I verified with tcpdump that UDP checksums are present and OK for the return traffic from iLO2. So unless a network was corrupting data just enough that basic UDP checksums wouldn't catch it and RCMP+ checksums would (perhaps a stronger algorithm) then it's not a problem. Seems like a very edge case to me for a LAN configuration intended for MAAS.
