here is an example of this "in the wild". I installed the NFS server
on Windows 2016, and with frame 53 I did a "ln -s x y" over a NFS
mount from Linux. Then in frame 83 I tried to read the attributes of
"y" and got the REPARSE_TAG_NOT_HANDLED error message.
I don't think any of this is a protocol violation, so I think this
needs to be documented.
