I think that there is an analogy. Both function could be used for receiving 
_frames_. eth_receive() for ethernet frames and Linux recv() for UDP frames.

Maybe I have used bad example. When application prepares a buffer
and chooses it's size to be less than interface MTU it means that application 
is not able to process larger packets. U-Boot should not expect that simple
application using API is able to handle every possible case (for example
9k packets on gigabyte ethernet).
