According to ETSI TS 102 771 (GSE implementation guidelines), "mandatory
extension headers" - when GSE's protocol type field is (strictly) less than 256
(0x100) - are of 'pre-defined length (and format) that must be known by all GSE
receivers'.
As a consequence, I think it is better to not dissect them and display such
headers as part of GSE PDU.
