Change subject: m3ua: Validate IE lengths of ASPTM & ASPSM messages ...................................................................... m3ua: Validate IE lengths of ASPTM & ASPSM messages Since all IEs in APTM and ASPSM messages are Optional, and until recently we only validated presence of mandatory IEs, there were no related structs for such messages. Now that we validate lengths of IEs, add the definitions for those messages too.
