Hi, Konrad

I want to distrub you again.

Finally, I found something, after I enabled ath11k boot dbg, I got my
id_string='bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=255`

With qca-swiss-army-knife (see [1])

$ ./ath11k-bdencoder -e board-2.bin | grep -i "$id_string"
bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=255.bin created size: 60048

It have already been here. So that means I don't need to extract from
Windows. I just extract it from linux-firmware then give it a variant
name and send patches to ath11k, right?
