Support of tap mode?

[Lê Minh Quân]

I encounter a problem when trying to run namespace-OpenVPN in dev tap

When I run dev tun, It works just fine. Can you add support for tap mode ?

Thanks for the report. I'd have to look deeper into what kind of environment variables openvpn publishes for a tap adapter. However, a lot of the existing code is specific to layer 3 (e.g., adding the IP address and the routes), so I suspect that for tap, it may be easier to write a separate script altogether.
