   What would be examples of this?  TCP/UDP inside of IPV6? Are there 
   other examples?  And is the expectation that the controller 
   automatically figures out where the TCP/UDP headers are or they are 
   told to the controller as some offset from a known location?

The chip merely does a 2's complement checksum over the entire
packet then sticks the complemented 16-bit result checksum at
the indicated offset from the beginning of the packet.

It is a raw 16-bit 2's complement checksum, sticking the
result at a configurable offset, nothing more.
