So that still leaves us with GSO introducing CE "spikes" into the network, that might not necessarily reflect what would happened if the meta-packet had been segmented before.... I note that rfc3168 probably will not care, since it will signal a CE mark for >= a full RTT anyway, but HFCCs will care.
Regards
Sebastian
