Jouni, any > preference? I think returning an error doesn't make sense. All the set-regulatory nl80211 command does is "set the domain to X". So why does it fail, if it was already X before the call. All the caller wants is to select domain X. That's what he gets in any case. Whether it was set to X or not before the call shouldn't matter. It's also confusing to get a "command failed" from iw. -- Greetings, Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
