That's not what link-layer dissectors should be doing; there was a bug, introduced a while ago, where the Ethernet dissector wasn't removing the FCS if it knew it was there, so perhaps that code was written during the period where that bug was present. I will remove that code from the PN dissector and leave behind a comment explaining why there is no FCS handling code there.
OK, done. Try it with the current SVN version of Wireshark.
BTW, is there a spec available for PROFINET Real-Time packets, for non-PROFINET members, either for free or for a not-too-high fee?
