Any suggestions or examples of successfully using > NL80211_CMD_REGISTER_FRAME in a separate user space program? This is (intentionally) not possible since only one of them should be responding. Depending on your use cases, you could open an additional monitor interface and look at all the frames there, or hook out of hostapd for example. Of course you can always hack out the check and change the delivery code to deliver to multiple userspace processes, but I don't think that's really a good change for upstream. johannes -- 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
