packet injection on 5G does not appear to work (2G does) - 8822bu

[raplin]

Noname 8822bu dongle on Ubuntu 5.4.0-65 (using backports branch)

Monitor mode (airmon, airodump) works fine on all channels, receives packets.

iw dev wlan0mon set channel 6
aireplay-ng --test wlan0mon

..works fine, sees APs and all injected packets work. Very good.

iw dev wlan0mon set channel 149
aireplay-ng --test wlan0mon

..still sees APs, but 0% of probes work.. Same on all 5Ghz channels I tried.

Just FYI. Thankyou for your work on this driver!
