This bug seems relatively harmless at the moment.  The most obvious
manifestation is a warning about a "partial flow" in the summary line

Example:
2    0    12.1.1.1    12.1.1.2    CFLOW    72    IPFIX partial flow (30/28
bytes)

There is no partial flow, but the padding bytes at the end of the packet are
triggering the warning.

Perhaps an expert warning should be added in the case of a real partial flow.
