@thaJeztah I noticed this flag is not included in the man page either. Where do I update that?

@dvdksn dockerd man page is here; https://github.com/docker/cli/blob/5d6612798a195b30edf4244ff06f18e80b1167d5/man/dockerd.8.md#synopsis

You can add the option to the "synopsis" section and the list of options under it

[thaJeztah]

Perhaps we should also have the networking section updated to (similar to the logging-driver options that can be set in daemon.json) mention that these defaults can be configured on the daemon.

revised—PTAL @thaJeztah :)

@dvdksn if you have time to do a cherry-pick for the 24.0 branch, then this will make its way to the docs 😅
