These are older Wifi 5 chips. RTL8821AU is 1x1, with or without
Bluetooth. RTL8812AU is 2x2, without Bluetooth.

Beamforming is not implemented. It looks like these chips need a
different implementation than what is in bf.c.

Speed tests with RTL8821AU: 137 Mbps download, 144 Mbps upload.
Speed tests with RTL8812AU: 344 Mbps download, 387 Mbps upload.

RTL8812AU should be faster, but my router is currently limited to
transmitting only one spatial stream due to a kernel bug.

Could you also mention operation mode (e.g. STA and AP) you have tested?
I think AP mode patch can't work for now, because I have not yet sent out
the fixes.

Patch 18/20 is quite large. Please give me some time to review.
