[En-Nut-Discussion] Checksum problem

[Harald Kipp]

There had been a problem with the original Liquorice checksum
calculation using inline assembly. I assumed some kind of
overflow, if too many bits in the data were set. I switched
to the C version, which had been prepared during ICCAVR porting
and the problem disappeared.

What's mysterious: The problem never seem to appear in TCP,
even after gigabytes of transfers.
