Partially resolves #97 in my case, as supplying data-ciphers field and compat-mode 2.3.0 fixes an issue of not being able to connect to old openvpn servers.
Tested only on 2.3.0ish server.
nm-applet overwrites these changes, sadly. nmcli does not.
Adds an option to supply a compat-mode parameter on ovpn file import, that will be passed to openvpn on connection.
How to test
The following is required:
- OpenVPN server 2.3.0 or older.
- Compiled and installed NetworkManager-openvpn plugin
