This is a simple bug in the SOME/IP dissector. When you use IPv6 the SOME/IP-SD does not correctly register the port to be dissected as SOME/IP. I forgot to return the port into the variable and always register port 0 instead of the correct one. :(

Bugfix was already prepared and will be pushed very soon.

This bug affects all Wireshark version with SOME/IP; i.e. 3.2.0 and newer.

added libwireshark version3.2 labels
