I think that I have found error, I generate DeliverSM with following code: ``` p := pdu.NewDeliverSM() p.Header().Status = 0 p.Header().Seq = m.Header().Seq + 1 f := p.Fields() f.Set(pdufield.DestAddrTON, m.Fields()[pdufield.SourceAddrTON])...

Here is how Wireshark see this part of message, please observe that message length byte is OK. Message is just prefixed with zero byte, so the last byte is cut...

As said I'm ready to pay for your time, maybe this one will help: https://www.freelancer.pl/projects/linux/develop-fix-small-fragment-golang/#/details
