From Audric Schiltknecht, bug 8521 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8521) 

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'.
