Thanks for your contribution! Could you please add a changelog fragment? Thanks.

(I think this is a new feature though, not a bugfix, since the module did not claim to support these options.)

@jeffmcutter @heaveaxy @haddystuff there are currently multiple open PRs by you three for the nmcli module (#5974, #6106, #6105, #6107, #6108, #6148) which are waiting for reviews. Since I don't know nmcli well and am not maintaining this module, I would be glad if you could review each other's PRs. I'll gladly help with making sure that all formalities are OK and with merging, but I cannot really judge the PR changes themselves. Thanks :)

[heaveaxy]

Looking correct. NM supports both in the form that defined in code.

[felixfontein]

Will merge by the end of the week if nobody objects.
