    That might help, but SIOCGIWNAME just gets a string that
    says what wireless mode the device is in, not the device
    name. Althought NetworkManager might use this for something

    All of the interesting config calls are probably happening
    via netlink, which doesn't get decoded by strace.

    But changes via netlink can get traced by using "ip" in monitor mode,
    try "ip monitor all" as root during such a NetworkManager run.
