That is for stuff set via set, but when it comes to the individual
network variables, not all of these have a default value other than
not defined, AFAIK, and setting them back to the defaults as far as I
can tell is impossible for some.

A example of this is the bssid variable. Once this has been set, I've
been unable to find any way to remove it via wpa_cli.

Any suggestions would be much appreciated.

Thanks. :)
