Osmocom Libraries » libosmo-sccp + libosmo-sigtran

ITU-T Q.713 states the DATA section of CR (and subsequent CREF or CC responses) is 130 bytes. This is different from the general 256 byte limit of DT1 or other messages. The same 130 byte limit applies to RLSD/RLC.

We should handle this in a generic way inside libosmo-sigtran so that applications trying to send > 130 byte payload in N-CONNECT.req will simply result in an empty CR followed by a delayed DT1 being sent. This way the applications don't have to care.
