Yep, that's it. But this is filled in smb_server/smb/reply.c
from SVAL(req->in.vwv, VWV(2));, whereas smbd3 fills it from
the flags field in the SMB header. Maybe the plain open
command is the better example. Here s3 gets the oplock info
from the header, I don't see how s4 does it.

I know I should write tests for this ... :-)
