    I think this is because OpenSSH's code is specific to OpenBSD.  Their
    tun(4) covers both our tun(4) and our tap(4), and has a different
    interface.  The fact that it compiles is actually the main bug.
 
    Now, it'd probably be good to add support for that in NetBSD, and it
    shouldn't be too difficult, given it's mostly the initialisation of
    devices that matters.  Well, the code might also be expecting a header
    or something on read packets, or even try to prepend one on written
    ones.
 
 I'm working on this -- no wonder the code in ssh/misc.c made no sense.
 I'm entirely new to NetBSD, however; can you suggest how I might
 rebuild libssh and usr.bin/ssh without running `build.sh -u build',
 which takes ten minutes rather than the ten seconds I'd hope for?
