Public bug reported:
On the Surface Pro 4 with USB Marvell Bluetooth/WLAN device, upgrading
from Ubuntu 18.04 with Linux 4.15.x to Ubuntu 20.04 with Linux 5.4.x,
only WPA2 Enterprise networks stop working, but other continue to work.
WPA: Failed to set GTK to the driver (alg=2 keylen=32 keyidx=1)
Starting Ubuntu 20.04.1 with Linux 4.15.x, the problem is gone. Testing
Ubuntu’s Linux mainline builds [1], the problem is still there in
5.4.68, but gone in 5.5-rc1.
We do not have the resources to bisect this further, as the user needs
the device back now.
