In the attached capture, frames 7, 8 and 10 are parts of the same SMB SET SD
request.

However, frames 8 and 10 are not reassembled, which causes Wireshark to fail to
dissect the request properly.

Frame 8 is labelled as a Session message and frame 10 as an NBSS Continuation
Message (with inconsistent capitalization.)

I have no patches for this yet. I am just filing the bug.

Capture and screen shot as attachments.
