Might be better with a const char * use

	case NL80211_CMD_RADAR_DETECT: {
		const char *type = "unknown";

		if (tb[NL80211_ATTR_RADAR_EVENT]) {
			switch (nla_get_u32(tb[NL80211_ATTR_RADAR_EVENT])) {
			case NL80211_RADAR_DETECTED:
				type = "radar detected";
				break;
			case NL80211_RADAR_CAC_FINISHED:
				type = "cac finished";
				break;
			case NL80211_RADAR_CAC_ABORTED:
				type = "cac aborted";
				break;
			case NL80211_RADAR_NOP_FINISHED:
				type = "nop finished";
				break;
			}
		}
		printf("radar event: (%s)\n", type);
	}
