     clarify tun(4) opening - set the mode and bring the interface up. also
     (re)sets the tun(4) layer 2 LINK0 flag for existing tunnel interfaces.

2dcddbfaf6 - (djm) [Makefile.in configure.ac includes.h misc.c] 
[openbsd-compat/port-tun.c openbsd-compat/port-tun.h] Add support
         for tunnel forwarding for FreeBSD and NetBSD. NetBSD's support is
         limited to IPv4 tunnels only, and most versions don't support the
         tap(4) device at all.

62a31c9fd0 - (djm) [misc.c] Disable tunnel code for non-OpenBSD (for now), enable 
again by providing a sys_tun_open() function for your platform and
   setting the CUSTOM_SYS_TUN_OPEN define. More work is required to match
   OpenBSD's tunnel protocol, which prepends the address family to the
   packet

[auth-options.c includes.h misc.c misc.h readconf.c servconf.c]
     [serverloop.c ssh.c ssh_config.5 sshd_config.5 configure.ac]
     two changes to the new ssh tunnel support. this breaks compatibility
     with the initial commit but is required for a portable approach.
     - make the tunnel id u_int and platform friendly, use predefined types.
     - support configuration of layer 2 (ethernet) or layer 3
     (point-to-point, default) modes. configuration is done using the
     Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and
     restricted by the PermitTunnel (yes|point-to-point|ethernet|no) option
     in sshd_config(5).

     [sshconnect.h sshd.8 sshd_config sshd_config.5]
     Add support for tun(4) forwarding over OpenSSH, based on an idea and
     initial channel code bits by markus@. This is a simple and easy way to
     use OpenSSH for ad hoc virtual private network connections, e.g.
     administrative tunnels or secure wireless access. It's based on a new
     ssh channel and works similar to the existing TCP forwarding support,
     except that it depends on the tun(4) network interface on both ends of
     the connection for layer 2 or layer 3 tunneling. This diff also adds
     support for LocalCommand in the ssh(1) client.

     ok djm@, markus@, jmc@ (manpages), tested and discussed with others

     implement support for X11 and agent forwarding over multiplex slave
     connections. Because of protocol limitations, the slave connections inherit
     the master's DISPLAY and SSH_AUTH_SOCK rather than distinctly forwarding
     their own.
