Hi,

James brought up a "we need a v7 here"...

If you call "openvpn --dev tap --dev-node utun0", I think the current
code will open an utun device, but the rest of OpenVPN will expect it
to be tappish...

21:18 <@jamesyonan> if utun doesn't support tap, then we need to make sure =
that=20
                    code will fall back to tuntap driver for tap tunnels

... so, two options

 a) utun can do TAP - in that case we need to add the necessary magic bits
    to convert the newly created utun into an utap

 b) it can not do TAP (which I'd expect, tbh), so we should never open
    an utun device if the user wants a tap.

Arne, your call :-)
