The session cnt is not used at all nor stored, according to ts004-2-0-0-fragmented-data-block-transport 3.3, L366-L388.

Also it would be nice to have a callback for the FRAGMENTATION_SESSION_SETUP_REQ,, we could use this to prepare the storage,
and then this could also have a reason for frag_session_data_tmp.frag_group_data.descriptor.

with kind regards,
