Is this a mistake, report it before ioctl(SIOCSIWMODE) failed: Device or resource busy ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start wlan0 <#>' Sysfs injection support was not found either.
