Sometimes ago, I've sniffed some packet on a ethernet network between
two pc with linux os (kernel 2.6.7). I've seen something very strange:
these declared 1700 MTU, but it sent packets of 640. Well, I've tried to
looking for this about google and I've finded the TSO (TCP Segmentation
Offload), but I've developed my knowledge snd I've understood thath this
not send little packets, but normal ethernet packets.
What can you think?
Bye.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
