Currently, many options cannot be set during `nmcli connection add`. The workaround is to modify the connection in a second step.


I'd think it makes sense to add more options to configure a connection during creation.
For example, if a unknowing user adds a connection (which is autoconnect=yes by default), the connection could already be activating when he is calling `nmcli connection modify`.


But instead of adding supporting parameters one-by-one in `nmcli connection add`, how about the following:


nmcli connection \
  add COMMON_OPTIONS TYPE_SPECIFIC_OPTIONS IP_OPTIONS -- MODIFY_OPTIONS


This effectively combines add+modify in one command line. Any MODIFY_OPTIONS are of course optional. But when specifying them, the '--' becomes mandatory (otherwise command line parsing and completion becomes difficult and possibly ambiguous).


It should be simple to implement too by reusing large parts of the modify command handling.



One downside is, that bash completion how it is implemented for `connection modfiy` will not work with these new options. It'd be quite difficult for bash completion to figure out which options are valid for the not yet existing connection. The solution for this is RFE in bug 724860.
