Unless this is yet *another* thing added to the 3.1 "maintenance" release
(would the AT&T-IS people please indicate whether something is true of the
current S5R3 release or will be true when 3.1 comes out?), RFS doesn't
handle this.  As you point out, it requires somebody to translate every
"ioctl" argument to a standard form when it goes over the net.  Somewhere,
either on the client or the server side, the XDR format (or its equivalent,
although I think RFS uses XDR) for every possible "ioctl" argument needs to
be stored.
