See attached extract from a packet capture on an SCTP link carrying ISDN
(Q.921) traffic. Wireshark 1.12.0 incorrectly decodes this as RSL (Radio
Signalling Layer) and hence claims all the packets are malformed.
This appears to be a regression, though I'm not sure in what version it was
introduced. My colleague has wireshark 1.6.5 and it decodes fine there.
