What's the status here?

RTL8822BU and RTL8821CU USB drivers

All current out-of-tree Realtek drivers suffer from deadlock when deleting the interface with iw dev wlan0 del. And this is exactly what OpenWrt does during AP configuration. Either the driver or mac80211.sh OpenWrt script should be patched.
